An matrix is called upper triangular if whenever .How many multiplications of entries are used by the algorithm found in Exercise 41 for multiplying two n x n upper triangular matrices?Exercise 41: From the definition of the matrix product, describe an algorithm in English for computing the product of two upper triangular matrices that ignores those products in the computation that are automatically equal to zero

SolutionStep 1In this problem we have to find the number of multiplication required to multiply two n x n upper triangular matrices.
