Scott,
Thanks a lot for this helpful program.
I wasn't aware of matsum. The package
is great.
Cheers.
Amadou.

sysuse auto,clear
tab rep fore [aw = mpg], matcell(A) col nof
matsum A, col(colA)
matrix C1 = (A[1...,1]/colA[1,1])*100
matrix C2 = (A[1...,2]/colA[1,2])*100
matrix D = C1, C2
matrix list D, format(%9.2f)

This uses Jeroen Weesie's -matsum- which is part of -matfunc- (STB-39
dm49).

Hope this helps,
Scott
