linear_solver module

Linear solvers wrapper.

class gemseo.utils.linear_solver.LinearSolver

Bases: object

Solve a linear system Ax=b.

Constructor.

solve(a_mat, b_vec, linear_solver='lgmres', **options)

Solve the linear system \(Ax=b\).

Parameters:

• a_mat – The matrix \(A\) of the system, can be a sparse matrix.

• b_vec (Sized) – The second member \(b\) of the system.

• linear_solver (str) –

  The name of linear solver.

  By default it is set to “lgmres”.

• **options – The options of the linear solver.

Returns:

The solution \(x\) such that \(Ax=b\).
