Here we will solve different types of Problems on Matrix Multiplication. 1. If A = \(\begin{bmatrix} 1 & -2 & 1\\ 2 & 1 & 3 \end{bmatrix}\) and B = \(\begin{bmatrix} 2 & 1\\ 3 & 2\\ 1 & 1 \end{bmatrix}\), write down the matrix AB. Would it be possible to find the product of BA? If so, compute it, and if not, give reasons. Solutions:

In the realm of linear algebra, a matrix is a structure composed of elements arranged in rows and columns. An m × n matrix consists of m rows and n columns. If a matrix has an equal number of rows and columns, it is referred to as a square matrix. Matrix multiplication refers to the process of performing multiplication operations with matrices.

Answer: a Explanation: Since The Coppersmith-Winograd algorithm multiplies the matrices in O(n 2.37) time.The time complexity of recursive multiplication of two square matrices by Strassen’s Method is found to be O(n 2.80).Therefore, Coppersmith-Winograd algorithm better than Strassen’s algorithm in terms of time complexity.

Matrix multiplication is a fundamental operation in linear algebra, which involves multiplying two matrices to obtain a new matrix. It is an essential tool in various fields such as physics, computer science, and engineering. Matrix multiplication combines the elements of two matrices in a specific way to produce the resulting matrix.
