Bases:
ScipyKrylovSolverThe LinearBicgstabSolver is an interface to the Bicgstab solver in Scipy, with no preconditioning by default.
Create a Solver object.
- Parameters:
tolerance (
float) – Required relative error tolerance.absolute_tolerance (
float) – Required absolute error tolerance.criterion (
{'default', 'unscaled', 'RHS', 'matrix', 'initial', 'legacy', }) – Interpretation oftolerance. See Convergence for more information.iterations (
int) – Maximum number of iterative steps to perform.precon – 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
