movfun() does not respect the class of the input.  Example code:


xs = single (1:10);
y = movfun (@mean, xs, 3);
class (y)
=> double


Matlab correctly returns "single".

Another issue is an error when requesting movfun work on a dimension with zero
elements.  Sample code:


o = ones (2, 0, 3);
y = movfun (@mean, o, 3, 2);
error: movslice: N must be a positive integer
