I have a question about matrix multiplication. I have 3 matrix which are Ce matrix and its dimension is 3x3 . The second matrix is Be and it is 3x18x2 and the third matrix is del matrix and its dimension is 18x1.
I want to multiply three matrix as Ce . Be[[, , 1]] . del and Ce . Be [[, , 2] . del
If Be matrix is just 3x18 there is no problem but here its third dimension is 2 and I dont know how to multiply each of them. Could you help me ?
