SparseGMRES(_:)

Declaration

func SparseGMRES(_ options: SparseGMRESOptions) -> SparseIterativeMethod

Parameters

• options:

  The options to use when creating the GMRES method, such as the maximum number of iterations to perform.

Return Value

A SparseIterativeMethod structure that represents a generalized minimal residual (GMRES) method.

Discussion

Use GMRES to solve Ax = b when A is symmetric indefinite or unsymmetric.

For symmetric positive-definite systems, use SparseConjugateGradient(_:). For rectangular or singular systems, use SparseLSMR(_:).
