st: Novice Mata question

[Adrian Mander <Adrian.Mander@mrc-hnr.cam.ac.uk>]

I wanted to write a function in Mata that deletes rows in a column 
vector (or matrix) that contain 0.


The simplest sort of solution ( in English ) would be
matrix temp  = matrix temp taking out one row

but this assignment obviously can't be done because of conformability errors.

Do I need to use pointers to do this?

Or alternatively how can I delete a matrix in Mata so that I can 
create an intermediate matrix?

cheers
Ade
