Remarks

The Bi-Conjugate Gradient Stabilized (BiCGStab) solver is an 'improvement' of the standard Conjugate Gradient (CG) solver. Unlike the CG solver the BiCGStab can be used on non-symmetric matrices.
Note that much of the success of the solver depends on the selection of the proper preconditioner.

The Bi-CGSTAB algorithm was taken from:

Algorithm is described in Chapter 2, section 2.3.8, page 27

The example code below provides an indication of the possible use of the solver.
