- class bempp.api.linalg.iterative_solvers.IterationCounter(store_residuals, iteration_is_cg=False, operator=None, rhs=None)¶
Bases:
object
Iteration Counter class.
- property count¶
Return the number of iterations.
- property residuals¶
Return the vector of residuals.
- __call__(x)¶
Call.
- bempp.api.linalg.iterative_solvers.gmres(A, b, tol=1e-05, restart=None, maxiter=None, use_strong_form=False, return_residuals=False, return_iteration_count=False)¶
Perform GMRES solve via interface to scipy.
This function behaves like the scipy.sparse.linalg.gmres function. But instead of a linear operator and a vector b it takes a boundary operator and a grid function or a blocked operator and a list of grid functions. The result is returned as a grid function or as a list of grid functions in the correct spaces.
- bempp.api.linalg.iterative_solvers.cg(A, b, tol=1e-05, maxiter=None, use_strong_form=False, return_residuals=False, return_iteration_count=False)¶
Perform CG solve via interface to scipy.
This function behaves like the scipy.sparse.linalg.cg function. But instead of a linear operator and a vector b it takes a boundary operator and a grid function. The result is returned as a grid function in the correct space.
- bempp.api.linalg.iterative_solvers._gmres_single_op_imp(A, b, tol=1e-05, restart=None, maxiter=None, use_strong_form=False, return_residuals=False, return_iteration_count=False)¶
Run implementation of GMRES for single operators.
- bempp.api.linalg.iterative_solvers._gmres_block_op_imp(A, b, tol=1e-05, restart=None, maxiter=None, use_strong_form=False, return_residuals=False, return_iteration_count=False)¶
Run implementation of GMRES for blocked operators.
