autopdex.solver.linear_solve_scipy(mat, rhs, solver, verbose, free_dofs)

Solves a linear system using a specified SciPy solver.

Parameters:

• mat (bcoo) – JAX BCOO matrix representing the system’s tangent matrix.

• rhs (jnp.ndarray) – The (reduced/free) right-hand side vector.

• solver (str) – Type of solver to use. Options are ‘lapack’ or ‘umfpack’.

• verbose (int) – Verbosity level for logging.

• free_dofs (jnp.ndarray) – Boolean array indicating free degrees of freedom for Dirichlet boundary conditions.

Returns:

Solution vector to the linear system.

Return type:

sol (jnp.ndarray)
