# probnum.linalg¶

Linear Algebra.

This package implements probabilistic numerical methods for the solution of problems arising in linear algebra, such as the solution of linear systems.

## Functions¶

 problinsolve(A, b[, A0, Ainv0, x0, …]) Infer a solution to the linear system $$A x = b$$ in a Bayesian framework. bayescg(A, b[, x0, maxiter, atol, rtol, …]) Conjugate Gradients using prior information on the solution of the linear system.

## Classes¶

 An abstract base class for probabilistic linear solvers. MatrixBasedSolver(A, b[, x0]) Abstract class for matrix-based probabilistic linear solvers. AsymmetricMatrixBasedSolver(A, b, x0) Asymmetric matrix-based probabilistic linear solver. SymmetricMatrixBasedSolver(A, b[, A0, Ainv0, x0]) Symmetric matrix-based probabilistic linear solver. SolutionBasedSolver(A, b[, x0]) Solver iteration of BayesCG.
