Kronecker product

[Giovanni]

Hello all.
I would like to implement the Kronecker product between 2 matrices.
Can someone help me? I have version 3.0.2 of Lapack.
I should implement something of this sort:

W = kron (WW, eye (m));

Where eye (m) is a matrix identity

Thank you very much.

There is no user documented routine in LAPACK to directly compute the Kronecker product, but if you look in the TESTING/MATGEN directory the routines d/s/c/zlakf2 may be of some help. You could maybe extract part of the code from there.

Best wishes,

Sven Hammarling.

Thank you very much Sven, I try with this solution.

did anybody get this worked out?

The following link contains generic C++ and Fortran 90 codes that calculates Kronecker products of two matrices. One does not have to install any other libraries.
