3. DESCRIPTION OF PROGRAM OR FUNCTION

This program solves an eigenvalue problem zBx=Ax where A and B are real block tridiagonal matrices. This eigenvalue problem is derived from a reduced set of linear resistive MHD equations which is often employed to study tokamak plasma stability problem.

4. METHOD OF SOLUTION

Both the determinant and inverse iteration methods are employed.
[ top ]
5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM:  The eigenvalue z
must be real.
