Hello,
can any kind soul help me on the following point. I need a numerically
stable (old K&R style or ANSI) C code that gives *all* eigenvectors
*and* eigenvalues for a *real nonsymmetric* matrix. The size of
matrices to handle will be limited by about 15x15, performance in not
that critical but the lack of symmetry in the input matrix is.
I know such a thing has been coded in FORTRAN as part of EISPACK but I
need it in C.
I would appreciate C code or hints to references on proper algorithms
how to implement such a routine.
If you know anything that might help me could you please drop me a
email.
Thanx in advance,
MARKUS
