Browsing a variable during a function call
===

While running one of my programs, I need to scan through a rather large matrix (100*700) to identify irregularities.

My initial idea was to have a breakpoint in place when I need to do a data scan, but I'm not a fan of that solution.

What I'm looking for would be equivalent to calling `openvar('A')` during a function call (except I can't presently do that). The alternative, `disp` renders the matrix poorly.

Any hints?
