Bases:
PysparseMatrixSolverThe base pysparseSolver class.
Attention
This class is abstract. Always create one of its subclasses.
Create a Solver object.
- Parameters:
tolerance (
float) – Required residual tolerance.criterion (
{'default', 'initial', 'unscaled', 'RHS', 'matrix', 'solution', 'preconditioned', 'natural', 'legacy'}, optional) – Interpretation oftolerance. See Convergence for more information.iterations (
int) – Maximum number of iterative steps to perform.precon (
Preconditioner) – Preconditioner to use. Not all solver suites support preconditioners.
- DEFAULT_ITERATIONS = 1000¶
Default maximum number of iterative steps to perform
- DEFAULT_PRECONDITIONER = None¶
Default preconditioner to apply to the matrix
- DEFAULT_TOLERANCE = 1e-05¶
Default tolerance for linear solves unless criterion=”legacy”
- LEGACY_TOLERANCE = 1e-10¶
Default tolerance for linear solves if criterion=”legacy”
- __repr__()¶
Return repr(self).
- property default_tolerance¶
Default tolerance for linear solve
