Module sparse 

Iterative sparse linear solvers.

Provides matrix-free iterative methods for solving large sparse linear systems A * x = b. The solvers accept a closure spmv: F that computes the sparse matrix-vector product y = A * x, enabling use with any sparse matrix format or even matrix-free operators.

Solvers

• CG (cg): Conjugate Gradient for symmetric positive definite systems.
• BiCGSTAB (bicgstab): Biconjugate Gradient Stabilized for non-symmetric systems.
• GMRES(m) (gmres): Generalized Minimal Residual with restart for general systems.
• Direct (direct): Direct sparse solver via dense LU (for small-to-medium systems).
