I am trying to write a function that multiplies two 4x4 matrices. The only problem is with indexing. In openGL the matrices are oriented like soSo instead of creating a 2 dimensional array. people create a single array of 16. now when i go to multiply it becomes difficult. I can't seem to come up with a double for loop way to correctly multiply the matrices. Does anyone have any suggestions?Code:0 4 8 12 1 5 9 13 2 6 10 14 3 7 11 15
