Hi 
I am using the -matrix accum-command to programme some matrices. I am not altogether confident with what I am doing. Here is what I would like to achieve and what I am doing:

I want to programme the calculation of 1/3 SUM(xi)(i=1,..N)SUM(GijHij)(j=1,...,Y). Note, x=variable list. What I have done is to first calculate the SUM(GijHij)(j=1,...,Y), call the result, say GH. Then I use the following

matrix accum XGH= 1/3 varlist GH

So my question is, is this correct?

Thanks
