ProjectedRHSInformationOp

class probnum.linalg.solvers.information_ops.ProjectedRHSInformationOp

Bases: probnum.linalg.solvers.information_ops.LinearSolverInformationOp

Projected right hand side \(s_i \mapsto b^\top s_i = (Ax)^\top s_i\) of the linear system.

Obtain information about a linear system by projecting the right hand side \(b=Ax\) onto a given action \(s_i\) resulting in \(y_i = s_i^\top b\).

Methods Summary

__call__(solver_state)

Projected right hand side \(s_i^\top b = s_i^\top Ax\) of the linear system.

Methods Documentation

__call__(solver_state)[source]

Projected right hand side \(s_i^\top b = s_i^\top Ax\) of the linear system.

Parameters

solver_state (LinearSolverState) – Current state of the linear solver.

Return type

ndarray
