◆ solve()
Pure virtual Function that defines a solve method for an iterative solver.
- Parameters
-
SystemMatrix | reference to an sgpp::base::OperationMatrix Object that implements the matrix vector multiplication |
alpha | the sparse grid's coefficients which have to be determined |
b | the right hand side of the system of linear equations |
reuse | identifies if the alphas, stored in alpha at calling time, should be reused |
verbose | prints information during execution of the solver |
max_threshold | additional abort criteria for solver, default value is 10^-9! |
Implemented in sgpp::solver::BiCGStab, and sgpp::solver::ConjugateGradients.
