Hi

I just noticed that conv2 does not accept the number of dimensions. Obviously
on the following example I'm giving crap to the function so I should expect an
error but would be nice to get a more meaningful error. Specially since images
are loaded as MxNx3 by default:


octave:13> a = uint8 (randi (255, 10, 10, 3));
octave:14> conv2 (a, ones(3))
error: invalid conversion of uint8 matrix to Matrix


The error even suggests that there's a problem on the the type but making it a
double just returns "invalid conversion of NDArray to Matrix". Same goes for
the seconed argument.
