Hello all,

I have two data sets; a data file, call this A, which is 41000 rows x 130
columns, and another file,call this B, 130 rows by 50 columns.

I want to multiply A and B (C=AxB). It would be ideal to treat A and B as
matrices and use matrix multiplication but the maximum matrix size is 11000
x 11000 (we run Stata 7.0 SE). Is there a way around this? If not, are there
any suggestions of how else to do this? I don't want to cut matrix A (or B)
into smaller data sets (matrices).  

Thanks in advance
Natalie
