- _A_r_g_u_m_e_n_t_s:
-
- x : a matrix. The first nc columns of the upper
- triangle contain the Choleski decomposition
- of the matrix to be inverted.
-
- size : the number of columns of x containing the
- choleski decomposition.
-
- _V_a_l_u_e:
-
- This matrix uses the given Choleski decomposition to
- invert the original positive definite matrix. It
- returns the inverse of the decomposed matrix.
