void PCGMSolve_sparse (  vector  sol, const sparse  A, const vector  b, sparse *  PC, double *  state )

Solve A*sol=b with PC - preconditioner (either filled or will be returned), state - parameters for solution: state[0]=MaxIter(max. iterations) state[1]=epsilon(precision/relative) state[2]=print residuals each iteration state[3]=GMRES restarts state[4]=print residuals each iteration state[5]=show 1 - header, 2 - convergent, 4 - nonconvergent (logical addition) state[6]=precision(absolute) state[7]= state[8]=OUTPUT: no. of performed iterations state[9]=achieved precision
