Ith row and jth column

WebIn other words, the ijth entry of AB is the dot product of the ith row of A with the jth column of B. 9. Note that matrix multiplication is not commutative. If A is n × m and B is m × k, where k 6= n, then AB is defined, but BA is not. Even if k = n, it is not generally true that AB = BA. 10. Let A, B and C be matrices and k a scalar. Then, WebA simple solution is to traverse the matrix and if we encounter any cell (i, j) that has value 0, change each element in the row i and column j to some arbitrary value other than 0 or 1. Later traverse the matrix once again and replace all elements with assigned value to 0. The algorithm can be implemented as follows in C++, Java, and Python: C++.
