General usage notes

• This module is meant for matrix manipulation and can carry out various operations. The matmath mmodule can carry various mathematical operations like addition, subtraction, multiplication and exponentiation along with Matrix-defined function like inverse, rotation, transpose, etc.
• It can also be used in finding determinant, inverse, transpose and adjoin of a matrix.
• The matrix/matrices should contain only numbers (i.e. <class 'int'>, <class 'float'> or <class 'complex'>) and not letters (i.e <class 'str'>) in order to avoid error.
• a few functions (example - matAdd(), matSub(), matMul(), adj(), det() and inverse()) may throw an error due to incompatibility of the matrices with the function.

Functions and their uses

Functions	Description
adj	Returns the adjoint of the matrix multiplied by the multiplication factor. Default value of mul(multiplication factor) is 1.
compatAS	Returns True if matrices are compatible for addition/subtraction else returns False.
compatM	Returns True if matrices are compatible for multiplication else returns False.
cut	Returns a smaller matrix by removing the required row and column. The default of row and column is 0.
det	Returns the determinant of the matrix (if and only if the matrices are compatible for multiplication) multiplied by the multiplication factor. Default value of mul (multiplication factor) is 1.
Identity	Returns an identity matrix of order N x N multiplied by the multiplication factor. Default value of mul (multiplication factor) is 1.
inv	Returns the inverse of the matrix (if and only if the matrices are compatible) multiplied by the multiplication factor. Default value of mul (multiplication factor) is 1.
isDiagonal	Returns True if matrix is a diagonal matrix else returns False.
isIdentity	Returns True if matrix is an identity matrix else returns False.
isLTriangular	Returns True if matrix is a lower triangular matrix else returns False.
isMatrix	Returns True if matrix is a valid matrix else returns False.
isNull	Returns True if matrix is a null matrix else returns False.
isSkewSymmetric	Returns True if matrix is a skew symmetric matrix else returns False.
isSquare	Returns True if matrix is a square matrix else returns False.
isSymmetric	Returns True if matrix is a symmetric matrix else returns False.
isUTriangular	Returns True if matrix is an upper triangular matrix else returns False.
matAdd	Returns the sum matrix (i.e. A + B), provided the matrices are compatible.
matMul	Returns the product matrix (i.e. AB), provided the matrices are compatible.
matSub	Returns the difference matrix (i.e. A - B), provided the matrices are compatible.
Null	Returns a null matrix of order N x M. If only 1 parameter is given returns a null matrix of order N x N.
order	Returns the order of the matrix as a tuple of the form (rows, columns).
power	Returns the matrix representing the nth power of matrix A, provided the matrix is square matrix.
rotate	Returns a matrix which is formed by rotating the given matrix, n times, in clockwise sense.
scalarMul	Returns the scalar product of A and n (i.e. nA).
trace	Returns the trace of the matrix (i.e the product of elements on the diagonal) if possible.
transpose	Returns the transpose of the matrix.
