Follow-up Comment #1:

Thanks for the report. I can confirm the error you are seeing with your given
function.

I modified it like so to make it work:


function y = fun(x)
      y = zeros(size(x));
      I = (x < 0) ;
      y(I) = 1 ;
      y(~I) = -1 ;
end


The important distinction being that the return value has the same size and
shape as the input. Your example returned a row vector regardless of whether
the input was a row, column, or matrix.

I think the error checking could be improved to make this clearer, as well as
the docstring. Suggestions?
