LinearStability

LinearStability	nroot #(in)
	rtolv #(rn)
	[eigensolverparams #(...)]

Solves linear stability problem. Only first nroot smallest eigenvalues and corresponding eigenvectors will be computed. Relative convergence tolerance is specified using rtolv parameter.

The eigensolverparams parameter describes the sparse linear solver attributes and is explained in section 5.2. Can be used in parallel mode. The input record must be the same for all processors. Parallel version requires PETSc and SLEPc modules.
