A simple and efficient module for matrix manipulation.
When installing the matmath module for python, it is recommended that you check if you have python 3.6 or above. To install matmath, goto a terminal and run:
pip install matmath
To upgrade matmath, run:
pip install --upgrade matmath
The Matrix and Vector classes support all mathematical operations like addition, subtraction, multiplication, division, matrix multiplication, etc. Apart from that, the Matrix class also supports the following functions:
| Functions | Description |
|---|---|
.adjoint() |
Returns the adjoint of the matrix. |
.adj() |
Alias of .adjoint() |
.cofactor() |
Returns the cofactor of the matrix. |
.copy() |
Returns a copy of the matrix. |
.cut() |
Returns a smaller matrix by removing the required row and column. The default of row and column is None. |
.determinant() |
Returns the determinant of the matrix (if mathematically possible). |
.det() |
Alias of .determinant(). |
.inverse() |
Returns the inverse of the matrix (if mathematically possible) multiplied by the multiplication factor. |
.inv() |
Alias of .inverse(). |
.is_diagonal() |
Tells if input is a diagonal matrix. |
.is_identity() |
Tells if input is an identity matrix. |
.is_lower_triangular() |
Tells if input is a lower triangular matrix. |
.is_null() |
Tells if input is a null matrix. |
.is_skew_symmetric() |
Tells if input is a skew symmetric matrix. |
.is_square() |
Tells if input is a square matrix. |
.is_symmetric() |
Tells if input is a symmetric matrix. |
.is_upper_triangular() |
Tells if input is an upper triangular matrix. |
.order() |
Returns the order of the matrix as a tuple of the form (rows, columns). |
.rotate() |
Returns a matrix which is formed by rotating the given matrix, n times, in clockwise sense. |
.trace() |
Returns the trace of the matrix, if mathematically possible. |
.transpose() |
Returns the transpose of the matrix. |
identity() |
Returns an identity matrix of order N x N multiplied by the multiplication factor. |
zero() |
Returns a null matrix of order N x M. If only 1 parameter is given returns a null matrix of order N x N. |
| Method | Description |
|---|---|
argument |
Returns the argument of the vector. |
cross_product |
Cross product of the vector with respect to another vector. |
dot_product |
Dot product of the vector with respect to another vector. |
is_parellel |
Tells whether the two vectors are parellel or not. |
is_unit |
Tells whether the vector is a unit vector or not. |
magnify |
Magnifies a vector. |
modulus |
Returns the modulus of the vector. |
rotate |
Rotates the 2d vector in 2D space. |
unit_vector |
Returns the unit vector in the direction of the vector. |
x |
Returns the 1st component of the vector. |
y |
Returns the 2nd component of the vector. |
z |
Returns the 3rd component of the vector. |
