Create tridiagonal matrix in Simulink

Hi there,

In SIMULINK I have the sudiagonal, diagonal and superdiagonal of a matrix as three vectors. Now I am looking to build the resulting matrix.

If we were in MATLAB I would have v1, v2, v3 and I would want A such that:

A = gallery('tridiag', v1, v2, v3);

Does anyone know a way to do that in SIMULINK?

Tanks a lot
