Time complexity: O(n 3).It can be optimized using Strassen’s Matrix Multiplication. Theorem 3 Given matrices A 2Rm l, B 2Rl p, and C 2Rp n, the following holds: A(BC) = (AB)C Proof: Since matrix-multiplication can be understood as a composition of functions, and since compositions of functions are associative, it follows that matrix-multiplication is associative Theorem 4 Given matrices A 2Rm n and B 2Rn p, the following holds: The program for matrix multiplication is used to multiply two matrices. A matrix is a 2-D array which means a list inside a list. Let us see with an example: To work out the answer for the 1st row and 1st column: Want to see another example? Example 1. We should have basic knowledge on the representation of two dimensional matrix in C. Here is three two dimensional matrix a, b and c. a for matrix A, b for matrix B, and c for matrix C. which holds the multiplication result.i, j, k are control variable and sum is needed to hold the summation of the consecutive two products. A matrix is known as a square matrix when its number of rows is equal to the number of columns. C Programs. To multiply two matrices, their dimension should be the same and it should be a square matrix. Then we are performing multiplication on the matrices entered by the user.
