About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Nullary

Apply a nullary callback and assign results to elements in a strided output array.

Installation

npm install @stdlib/strided-base-nullary

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var nullary = require( '@stdlib/strided-base-nullary' );

nullary( arrays, shape, strides, fcn )

Applies a nullary callback and assigns results to elements in a strided output array.

var Float64Array = require( '@stdlib/array-float64' );

function fill() {
    return 3.0;
}

var x = new Float64Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ] );

nullary( [ x ], [ x.length ], [ 1 ], fill );
// x => <Float64Array>[ 3.0, 3.0, 3.0, 3.0, 3.0, 3.0, 3.0, 3.0 ]

The function accepts the following arguments:

• arrays: array-like object containing one strided output array.
• shape: array-like object containing a single element, the number of indexed elements.
• strides: array-like object containing the stride length for the strided output array.
• fcn: nullary function to apply.

The shape and strides parameters determine which elements in the strided output array are accessed at runtime. For example, to index the first N elements of the strided output array in reverse order,

var Float64Array = require( '@stdlib/array-float64' );

function fill() {
    return 3.0;
}

var x = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0, -6.0 ] );

nullary( [ x ], [ 3 ], [ -1 ], fill );
// x => <Float64Array>[ 3.0, 3.0, 3.0, -4.0, -5.0, -6.0 ]

Note that indexing is relative to the first index. To introduce an offset, use typed array views.

var Float64Array = require( '@stdlib/array-float64' );

function fill() {
    return 3.0;
}

// Initial arrays...
var x0 = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0, -6.0 ] );

// Create offset views...
var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element

nullary( [ x1 ], [ 3 ], [ 1 ], fill );
// x0 => <Float64Array>[ -1.0, 3.0, 3.0, 3.0, -5.0, -6.0 ]

nullary.ndarray( arrays, shape, strides, offsets, fcn )

Applies a nullary callback and assigns results to elements in a strided output array using alternative indexing semantics.

var Float64Array = require( '@stdlib/array-float64' );

function fill() {
    return 3.0;
}

var x = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0 ] );

nullary.ndarray( [ x ], [ x.length ], [ 1 ], [ 0 ], fill );
// x => <Float64Array>[ 3.0, 3.0, 3.0, 3.0, 3.0 ]

The function accepts the following additional arguments:

• offsets: array-like object containing the starting index (i.e., index offset) for the strided output array.

While typed array views mandate a view offset based on the underlying buffer, the offsets parameter supports indexing semantics based on starting indices. For example, to index the last N elements in the strided output array,

var Float64Array = require( '@stdlib/array-float64' );

function fill() {
    return 3.0;
}

var x = new Float64Array( [ -1.0, -2.0, -3.0, -4.0, -5.0, -6.0 ] );

nullary.ndarray( [ x ], [ 3 ], [ -1 ], [ x.length-1 ], fill );
// x => <Float64Array>[ -1.0, -2.0, -3.0, 3.0, 3.0, 3.0 ]

Examples

var discreteUniform = require( '@stdlib/random-base-discrete-uniform' ).factory;
var filledarray = require( '@stdlib/array-filled' );
var nullary = require( '@stdlib/strided-base-nullary' );

var x = filledarray( 0.0, 10, 'generic' );
console.log( x );

var shape = [ x.length ];
var strides = [ 1 ];
var offsets = [ 0 ];

nullary.ndarray( [ x ], shape, strides, offsets, discreteUniform( -100, 100 ) );
console.log( x );

C APIs

Character codes for data types:

• x: bool (boolean).
• z: complex128 (double-precision floating-point complex number).
• c: complex64 (single-precision floating-point complex number).
• f: float32 (single-precision floating-point number).
• d: float64 (double-precision floating-point number).
• k: int16 (signed 16-bit integer).
• i: int32 (signed 32-bit integer).
• s: int8 (signed 8-bit integer).
• t: uint16 (unsigned 16-bit integer).
• u: uint32 (unsigned 32-bit integer).
• b: uint8 (unsigned 8-bit integer).

Function name suffix naming convention:

stdlib_strided_<output_data_type>[_as_<callback_return_data_type>]

For example,

void stdlib_strided_d(...) {...}

is a function which accepts one double-precision floating-point strided output array. In other words, the suffix encodes the function type signature.

To support callbacks whose return values are of a different data type than the strided output array data type, the naming convention supports appending an as suffix. For example,

void stdlib_strided_f_as_d(...) {...}

is a function which accepts one single-precision floating-point strided output array. However, the callback returns double-precision floating-point numbers. Accordingly, the output value needs to be cast using the following conversion sequence

// Evaluate the callback:
double out = f();

// Convert the callback return value to single-precision:
y[ i ] = (float)out;

STDLIB_STRIDED_NULLARY_LOOP_INLINE( tout, expr )

Macro for a nullary loop which inlines an expression.

STDLIB_STRIDED_NULLARY_LOOP_INLINE( double, *out = (double)1.0 )

The macro expects the following arguments:

• tout: output strided array element type.
• expr: expression to inline.

In addition to the variables defined by the STDLIB_STRIDED_NULLARY_LOOP_PREAMBLE macro, the macro defines the following variables:

• out: <tout>* pointer to an output strided array element.

The macro expects a provided expression to store the result via *out.

#define STDLIB_STRIDED_NULLARY_LOOP_INLINE( tout, expr )   \
    STDLIB_STRIDED_NULLARY_LOOP_PREAMBLE {                 \
        tout *out = (tout *)op1;                           \
        expr;                                              \
    }

STDLIB_STRIDED_NULLARY_LOOP_CLBK( tout )

Macro for a nullary loop which invokes a callback.

STDLIB_STRIDED_NULLARY_LOOP_CLBK( double )

The macro expects the following arguments:

• tout: output strided array element data type.

In addition to the variables expected by STDLIB_STRIDED_NULLARY_LOOP_PREAMBLE, the macro expects the following variables to be defined:

• f: nullary callback.

#define STDLIB_STRIDED_NULLARY_LOOP_CLBK( tout )           \
    STDLIB_STRIDED_NULLARY_LOOP_PREAMBLE {                 \
        *(tout *)op1 = (tout)f();                          \
    }

STDLIB_STRIDED_NULLARY_LOOP_CLBK_RET_NOCAST( tout )

Macro for a nullary loop which invokes a callback and does not cast the return callback's return value (e.g., a struct).

#include "stdlib/complex/float64/ctor.h"

STDLIB_STRIDED_NULLARY_LOOP_CLBK_RET_NOCAST( stdlib_complex128_t )

The macro expects the following arguments:

• tout: output strided array element data type.

In addition to the variables expected by STDLIB_STRIDED_NULLARY_LOOP_PREAMBLE, the macro expects the following variables to be defined:

• f: nullary callback.

#define STDLIB_STRIDED_NULLARY_LOOP_CLBK_RET_NOCAST( tout )                    \
    STDLIB_STRIDED_NULLARY_LOOP_PREAMBLE {                                     \
        *(tout *)op1 = f();                                                    \
    }

STDLIB_STRIDED_NULLARY_LOOP_CLBK_RET_CAST_FCN( tout, cout )

Macro for a nullary loop which invokes a callback whose return values should be cast to a different type via casting functions.

#include "stdlib/complex/float32/ctor.h"
#include "stdlib/complex/float64/ctor.h"

STDLIB_STRIDED_NULLARY_LOOP_CLBK_RET_CAST_FCN( stdlib_complex64_t, stdlib_complex128_to_complex64 )

The macro expects the following arguments:

• tout: output strided array element data type.
• cout: function for casting an callback's return value to the output array data type.

In addition to the variables expected by STDLIB_STRIDED_NULLARY_LOOP_PREAMBLE, the macro expects the following variables to be defined:

• f: nullary callback.

#define STDLIB_STRIDED_NULLARY_LOOP_CLBK_RET_CAST_FCN( tout, cout )            \
    STDLIB_STRIDED_NULLARY_LOOP_PREAMBLE {                                     \
        *(tout *)op1 = cout( f() );                                            \
    }

Examples

#include "stdlib/strided/base/nullary.h"
#include <stdint.h>
#include <stdio.h>
#include <inttypes.h>

// Define a callback:
static double fill( void ) {
    return 10.0;
}

int main( void ) {
    // Create underlying byte arrays:
    uint8_t out[] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

    // Define a pointer to an array containing pointers to strided arrays:
    uint8_t *arrays[] = { out };

    // Define the strides:
    int64_t strides[] = { 8 }; // 8 bytes per double

    // Define the number of elements over which to iterate:
    int64_t shape[] = { 3 };

    // Apply the callback:
    stdlib_strided_d( arrays, shape, strides, (void *)fill );

    // Print the contents of the output array:
    uint8_t *op1 = out;
    for ( int64_t i = 0; i < shape[0]; i++, op1 += strides[0] ) {
        const double v = *(double *)op1;
        printf( "out[ %"PRId64" ] = %lf\n", i, v );
    }
}
