void solve_lin_alg_system	(	double *	lhs,
		double *	rhs,
		FILE *	out
	)

function solves system of linear algebraic equations by the modified conjugate gradient method Lagrange multipliers are computed first and then displacements are obtained for more details see Kruis: Domain Decomposition Methods for Distributed Computing. Saxe-Coburg, 2006.
