Options for creating a generalized minimal residual (GMRES) method.
Declaration
struct SparseGMRESOptionsOverview
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(_:).
