store matrices in a matrix

[veni arakelian]

Dear all

I have a short question. I run a rolling VAR estimation and I'd like to store, for example the coefficients from each estimation is a 3x2 matrix (denote varcoeff{!step}), in a matrix, say 'varcoeff', whose size changes in each iteration.

How can I write correctly the following varcoeff(step,step+3)=varcoeff{!step}?

Thanks,

V.

Use the matplace function.
