With chained matrix multiplications such as A*B*C, you might be able to improve execution time by using parentheses to dictate the order of the operations. Consider the case of multiplying three matrices with A*B*C, where A is 500-by-2, B is 2-by-500, and C is 500-by-2. With ...

I have two 3D-matrices A(M,N,I) and B(M,N,I) with complex numbers. Values of M,N and I are large say in the range 500-5000. An easy way to do matrix multiplication is to use for loop for I, but it hugely slows down my rest of the code because I have to do this multipl...

POJ3318--Matrix Multiplication 随机化算法 Description You are given threen×nmatricesA,BandC. Does the equationA×B=Chold true? Input The first line of input contains a positive integern(n≤ 500) followed by the the three matricesA,BandCrespectively. Each matrix's description is a block ...
For example; given that matrix A is a 3 x 3 matrix, for matrix multiplication AB to be possible, matrix B must have size 3 x m where m can be any number of columns. This, as we shall see in a moment, is because of the way matrices are multiplied. This rule is the reason why...
The result of the multiplication of matrices Am×n and Bn×k the matrix Cm×k such that the element of the matrix C, standing in the i-th row and j-th column (cij), is equal to the sum of products of elements of the i-th row of the matrix A by the corresponding elements j-th...

Proposition (distributive property)Matrix multiplication is distributive with respect to matrix addition, that is, for any matrices , and such that the above multiplications and additions are meaningfully defined. Proof Proposition (associative property)Matrix multiplication is associative, that is, ...
Here you can perform matrix multiplication with complex numbers online for free. After calculation you can multiply the result by another matrix right there!
