Hello,
I am trying to multiply a matrix and a vector with proc iml, but I never used it,.
Basically, I already have the two datasets that I need, one MATRIX and one VECTOR.
I simply want the resulting vector of the multiplication of MATRIX*VECTOR in a new dataset with one variable named RESULT.
Better post is at IML forum, since it is a IML question.
data matrix;
set sashelp.class;
keep age weight height;
run;
data vector;
do vector=1 to 3;
output;
end;
run;
proc iml;
use matrix;
read all var _num_ into matrix;
close;
use vector;
read all var {vector};
close;
result=matrix*vector;
create result var {result};
append;
close;
quit;
Here's an introductory resource to PROC IML that I hope you'll find helpful. Rick also publishes "The DO Loop" blog for SAS.

In the future, I suggest you post IML questions to the Analytics / SAS/IML area. The Enterprise Guide area tends to get questions about the EG interface, and the IML folks don't tend to watch it.
