I need to multiply each column in matrix A with each row in matrix B. Where A and B are of dimensions (nxj), and n and j can be quite large (~50k). So I will get n matrices and each of them are of dimensions (jx
Firstly, we can only multiply two matrices when the number of columns in matrix A is equal to the number of rows in matrix B. Secondly, the first row of matrix A multiplied by the first column of matrix B gives us the first element in the matrix AB, and so on. ...
Multiplying multiple variables within an equationReally simple question, but with not using Matlab for the last 2 years I've forgotten and I can't find the answer anywhere.gives you 21 x 91 matrix, where each row corresponds to one of the u values, and each column corresponds to one of ...
