Public Functions

inline virtual int invert(size_t n, const mat_t &A, mat_t &A_inv)

Invert matrix A, returning the inverse in A_inv.

inline virtual int invert_det(size_t n, const mat_t &A, mat_t &A_inv, double &A_det)

Invert matrix A, returning the inverse in A_inv, and the determinant in A_det.

inline virtual double det(size_t n, const mat_t &A)

Determine the determinant of the matrix A without inverting.

inline virtual int invert_inplace(size_t n, mat_t &A)

Invert matrix A in place.
