- Function: int gsl_linalg_solve_symm_tridiag (const gsl_vector * diag, const gsl_vector * e, const gsl_vector * b, gsl_vector * x)
-
This function solves the general @math{N}-by-@math{N} system @math{A x =
b} where A is symmetric tridiagonal. The form of A for the
4-by-4 case is shown below,
- Function: int gsl_linalg_solve_symm_cyc_tridiag (const gsl_vector * diag, const gsl_vector * e, const gsl_vector * b, gsl_vector * x)

This function solves the general @math{N}-by-@math{N} system @math{A x =
b} where A is symmetric cyclic tridiagonal. The form of A
for the 4-by-4 case is shown below,
