Linear System Solvers --- LSS.h

This file defines (interval) linear system solvers computing an enclosure of the solution set. These methods are due to S.M. Rump.

Function: INTERVAL_VECTOR LSS (MATRIX A, VECTOR b, BOOL & ok)

Computes an enclosure of the solution set x of the linear system Ax=b. If the enclosure is possible, it is returned and ok is set to TRUE. Otherwise ok is set to FALSE and the return value is undefined.

Function: INTERVAL_VECTOR ILSS (INTERVAL_MATRIX A, INTERVAL_VECTOR b, BOOL & ok)

Computes an enclosure of the solution set x of the linear system Ax=b. If the enclosure is possible, it is returned and ok is set to TRUE. Otherwise ok is set to FALSE and the return value is undefined.
