> Do you mean this is a FORTRAN example that shows the problem, or one
that just happens to be FORTRAN? I'd be happy to check this as well if
you give me something to cut and paste. And tell me how to compile it if
I have to do that :)
This is a FORTRAN example that calls the problem function and with a 3 x 4
matrix, which is a problematic size. So it might fail. But you need to
have a configuration that is failing already, or it is not really of much
use.
And I have no idea how to compile it, run it, find the right libraries,
etc.
