Details:

This is a placeholder issue report.  During the first code sprint it was found
that permutation matrices can only be created of class double.  This might not
be a problem, however, we found C++ code for the double() function
(src/ov-re-mat.cc) that was checking for permutation matrices of type single.

Example Code:


x = eye(2)([2,1], :)
x =

Permutation Matrix

   0   1
   1   0

BUT

x = eye(2, "single")([2,1], :)
x =

   0   1
   1   0
