Estimado Sr Castro:

This is an Octave-Forge bug, and that project for the time being has a separate bug tracker located at http://octave.sourceforge.net/bugs.html

Kindly report your bug there.

I hope to some day soon unite the bug trackers, but for the moment I apologise for the convenience.

The function fspecial from the image package produces wrong results for the "motion" filter shape.

When the first parameter is set to "motion" and when the third parameter which then represents the orientation of the motion is set to something other than null degrees, then the resulting matrix only contains NA elements.

I have experienced this problem on a Cygwin installation.

Here is an example:

This is exampl produced correct results, but when I change the orientation parameter to 10 degrees, then

the returned matrix only contains NA elements. I would expect a correctly interpolated motion matrix here.
