Replying to [ticket:11528 kcrisman]:
> This was requested in the 2011 Sage MAA PREP workshop. Names deleted.
> {{{
> : Is there any way to delete specified rows or columns from an existing
matrix?
> : Hmm, I think that is possible, using a method.
> : I'll look.
> : - we can swap rows, scale rows, add mults of rows, create a matrix
from specified rows... but not that.
> : Would you find this useful? Is it in Matlab?
> : For list there is a method called pop
> : Right, but not for matrices.
> : if matrix is a list of list...
