data sets Date   Tue, 24 Jun 2003 15:51:15 +1000  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
