Comment (by jhpalmieri):
You might consider using `all` or `any`:
{{{
A = random_matrix(ZZ,5); A
def checkfunc(matrix, func):
return any(func(val)==True for val in matrix.list()) # untested
}}}
Also, I'm not sure that there is an iterator for the elements of a matrix.
I guess there's one for the rows (`mat.__iter__()`), and then I guess for
each row there's one (`row.iteritems()`). I don't see one for all of the
elements, though. (I tried searching the files in the `matrix` directory
for "yield" and didn't find much.)
