Aim:
Write a program to perform multiplication of two square matrices
Program:
row=int(input("Enter No of Rows for 1st Matrix:"))
column=int(input("Enter No of column for 1nd Matrix:"))
row1=int(input("Enter No of Rows for 2st Matrix:"))
column1=int(input("Enter No of column for 2nd Matrix:"))
if(column==row1):
X = [[int(input(("Enter value for X[",i,"][",j,"]:"))) for
j in range(column)] for i in range(row)]
Y = [[int(input(("Enter value for Y[",i,"][",j,"]:"))) for
j in range(column1)] for i in range(row1)]
result = [[0 for j in range(column1)] for i in range(row)]
print("result",result)
print("1st Matrix X:",X)
print("2st Matrix Y:",Y)
for i in range(len(X)):
for j in range(len(Y[0])):
for k in range(len(Y)):
result[i][j] += X[i][k] * Y[k][j]
for r in result:
print(r)
else:
print("Multiplication is not possible")
Output:
Enter No of Rows for 1st Matrix:2
Enter No of column for 1nd Matrix:2
Enter No of Rows for 2st Matrix:2
Enter No of column for 2nd Matrix:2
