Member Function Documentation

solve()

virtual void sgpp::solver::SLESolver::solve ( sgpp::base::OperationMatrix &  SystemMatrix, sgpp::base::DataVector &  alpha, sgpp::base::DataVector &  b, bool  reuse = false, bool  verbose = false, double  max_threshold = DEFAULT_RES_THRESHOLD  )

pure virtual

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.
