Matrix7

a library in pure python3 that allows you to use matrices and vectors easily

Setup

sudo pip install matrix7

How to use

Declarations

from matrix7 import Matrix, Vector

a = Matrix([
    [1,2,3,4,5,6,7],
    [101,102,103,104,105,106,107],
    [201,202,203,204,205,206,207],
])

b = Vector( [2,4,7,9] )

c = Vector( [2,4,7,9] , transpose = True )

printing

• print(a) :

|   1.00   2.00   3.00   4.00   5.00   6.00   7.00 |
| 101.00 102.00 103.00 104.00 105.00 106.00 107.00 |
| 201.00 202.00 203.00 204.00 205.00 206.00 207.00 |

• print(b) :

|   2.00 |
|   4.00 |
|   7.00 |
|   9.00 |

• print(c) :

|   2.00   4.00   7.00   9.00 |

properties

a.size    # (nb lines, nb cols)
a.trace   # only for nxn matricies
a.raw     # matrix or vector in normal python list format
a.gravity # only for vectors

operations

• normal python operations are used
• Matrix or Vector object is returned
• regular matrix/vector calculation rules apply

c = a + b
c = a - b
c = a * b

trasponse of matrix or vector

a.transpose()

generation

# vector containing 6 threes
vect = Vector.gen(6, 3)

# 3x4 matrix of zeroes
mat = Matrix.gen(3, 4, 0)

navigation

# matrix line 0 (Vector) or vector element (int, float ..etc)
a[0]
# matrix column 0 (Vector)
a(0)
# matrix element (0,0) (int, float ..etc)
a[0][0]
