Class linear_solver (o2scl_linalg)

O2scl : Class List

template<class vec_t = boost::numeric::ublas::vector<double>, class mat_t = boost::numeric::ublas::matrix<double>>
class linear_solver

A generic solver for the linear system \( A x = b \) [abstract base].

A generic solver for dense linear systems.

Those writing production level code should consider calling LAPACK directly as described in the Linear Algebra section of the User’s Guide.
