Webruns in time O(n3) and then show how we can do better using Strassen’s Algorithm. We will only consider dense matrix multiplication, in which most of the entries of the input matrices are nonzero. For sparse matrices, in which most of the entries are 0, there are algorithms for matrix multiplication that leverage this sparsity to get a better ... WebIn this context, using Strassen’s Matrix multiplication algorithm, the time consumption can be improved a little bit. Strassen’s Matrix multiplication can be performed only on square matrices where n is a power of 2. Order of both of the matrices are n × n. Divide X, Y and Z into four (n/2)× (n/2) matrices as represented below −
