Question

write an algorithm to find the matrix multiplication of two ID matrices

Answer 1

Let A and B be two matrices
Let n = number of rows in matrix A
Let p = number of columns in matrix B
Let m = number of columns in matrix A and number of rows in matrix B
Let C be a new matrix to store the multiplication of matrices A and B
For i --> 1 to n:
For j --> 1 to p:
Let temp = 0
For k --> 1 to m:
temp = temp + [ A(i)(k) * B(k)(j) ]
END
C(i)(j) = temp
END
END
return C
