I guess it is a matter of my complete ignorance in these issues, but could 
somebody on the thread elaborate a bit on why C++ implementations of matrix 
operations are supposed to suffer from low performance? What causes the C++ 
code doing the matrix inversion to be slow compared to its FORTRAN equivalent?
