Parameters

storedTriangle  MatrixTriangle

            = 'U':  Upper triangle of A is stored;
            = 'L':  Lower triangle of A is stored.
            

n  Int32

            The order of the matrix A.  N >= 0.
            

a  Array2D<TReal>

            A is TReal array, dimension (LDA,N)
            On entry, the triangular factor U or L from the Cholesky
            factorization A = UT*U or A = L*LT, as computed by
            DPOTRF.
            On exit, the upper or lower triangle of the (symmetric)
            inverse of A, overwriting the input factor U or L.
            

            The leading dimension of the array A.  LDA >= max(1,N).
            

info  Int32

            = 0:  successful exit
            < 0:  if INFO = -i, the i-th argument had an illegal value
            > 0:  if INFO = i, the (i,i) element of the factor U or L is
                  zero, and the inverse could not be computed.
            

This method corresponds to the LAPACK routine ?POTRI.
