Hi,
I am using mingw 32bit build of Octave on 64bit windows 7.
Consider this code snippet:
#include <octave/oct.h>
DEFUN_DLD (bugsingle, args, nargout,
"Reproducing the single complex diag. matrix bug. \n")
{
if(args(0).is_complex_type())
{
if(args(0).is_single_type())
{
octave_stdout << "Input is complex single." << "\n";
}
else if(args(0).is_double_type())
{
octave_stdout << "Input is complex double." << "\n" ;
}
}
return octave_value_list();
}
Calling it from octave results in:
Correct output:
octave:10> bugsingle(single(ones(3)*i))
Input is complex single.
Incorrect output:
octave:11> bugsingle(single(eye(3)*i))
Input is complex double.
I suspect there is something wrong with the specialized classes for the
diagonal matrices, but I am not able to track that down. Sorry.
