Is there a way to associate names with rows and columns of matrices? I would like to be able to read a file like... , C1, C2 R1, 1, 2 R2, 3, 4 And have a matrix [1,2;3,4] with the associated names attached. I was doing some financial analysis and spent a lot of time trying to ensure that there was no row or column swapping. cheers Worik
