but then I guess you will have to do again M[i,j].u=t.u right? So you have 2 record copy operations at each iteration. I do not think that it is a pointer to M[]. You save one pair of indexes but I am not sure how much time you are going to save. You should probably run some tests and compare the execution time. I'll be curios to know about any gain/loss in performance.
