Basic Operations For Matrices

SNMATRICES

---

• These Operations will work only ,if both the matrices are of same order

Matrix_Operations:

MODULE NAME:operations.py

1)Getting input matrix: Function:input_matrix(Number of rows,Number of columns)

2)Matrix Addition: Function:matrix_addition(matrixA,matrixB)

3)Matrix Subraction Function:matrix_subraction(matrixA,matrixB)

-4)Matrix Multiplication: -Function:matrix_multiplication(matrixA,matrixB)

SOURCE CODE

MATRIX ADDITION

def matrix_addition(A,B): mat_addition=[] for i in range(len(A)): c=[] for j in range(len(B[0])): c.append(A[i][j]+B[i][j]) mat_addition.append(c) print('Matrix Addition=') print(mat_addition)

MATRIX SUBRACTION

def matrix_subraction(A,B): mat_subraction=[] for i in range(len(A)): c=[] for j in range(len(B)): c.append(A[i][j]-B[i][j]) mat_subraction.append(c) print('Matrix Subraction=') print(mat_subraction)

MATRIX MULTIPLICATION

def matrix_multiplication(A,B): mul_result=[] for i in range(len(A)): c=[] for j in range(len(B[0])): result=0 for k in range(len(B)): result+=A[i][k]*B[k][j] c.append(result) mul_result.append(c) print('Matrix Multiplication=') print(mul_result)

INPUT MATRIX

def input_matrix(rows,columns): A=[] print('Enter the entries row wise:') a=[] for i in range(rows): a=[] for j in range(columns): a.append(int(input())) A.append(a) print('Input Matrix=') print(A)
