== Fortran matmul use ==
I am re working the Fortran example to use in a Delphi project.
The matrix multiply at the end of the example looks to be in the incorrect order.
I believe it should be.
polyfit = matmul( XTX, matmul(XT, vy))
I would appreciate if somebody with the Fortran language available could confirm.
