Python numpy library functions to perform basic matrix operations are as follows.
• C=numpy.add(A, B): Add two matrices A and B and store result in C.
• C=numpy.subtract(A, B): Subtract matrix B from matrix A and store result in C.
• C=numpy.divide(A, B): Divide matrix A by matrix B and store result in C.
• C=numpy.multiply(A, B): Multiply matrix A by matrix B and store result in C.
• C=numpy.sum(A): Form the sum of elements of matrix A and store result in c ∈ R.
• C=numpy.sum(A, axis = 0): Form the column wise summation of matrix A and
store result in
• C=numpy.sum(A, axis = 1): Form the row wise summation of matrix A, store
result in vector C.
