I have a matrix M, I want to create 3 additional matrices where each additional matrix has certain 3x3 column-slices of M multiplied by values in a vector, I will then store the resulting 3 new matrices in a list. ##create the initial matrix M <- matrix(1:20, nrow = 4) [,1] [...
In the multiplication of two matrices, the row elements of the first matrix are multiplied by the column elements of the second matrix. In matrix multiplication row value of the 1st matrix must be the same as the column value of the 2nd matrix. That means if 1st matrix is 3X3, then 2nd...
