gf_precond

The preconditioners may store REAL or COMPLEX values. They accept getfem sparse matrices and Matlab sparse matrices.

Calling Sequence

PC = gf_precond('identity')
PC = gf_precond('cidentity')
PC = gf_precond('diagonal', vec D)
PC = gf_precond('ildlt', spmat m)
PC = gf_precond('ilu', spmat m)
PC = gf_precond('ildltt', spmat m[, int fillin[, scalar threshold]])
PC = gf_precond('ilut', spmat m[, int fillin[, scalar threshold]])
PC = gf_precond('superlu', spmat m)
PC = gf_precond('spmat', spmat m)

Description
