Class Dpotri

    java.lang.Object
      org.netlib.lapack.Dpotri

    public class Dpotri

extends java.lang.Object

    Following is the description from the original
    Fortran source.  For each array argument, the Java
    version will include an integer offset parameter, so
    the arguments may not match the description exactly.
    Contact seymour@cs.utk.edu with any questions.

     *  Purpose
     *  =======
     *
     *  DPOTRI computes the inverse of a real symmetric positive definite
     *  matrix A using the Cholesky factorization A = U**T*U or A = L*L**T
     *  computed by DPOTRF.
     *
     *  Arguments
     *  =========
     *
     *  UPLO    (input) CHARACTER*1
     *          = 'U':  Upper triangle of A is stored;
     *          = 'L':  Lower triangle of A is stored.
     *
     *  N       (input) INTEGER
     *          The order of the matrix A.  N >= 0.
     *
     *  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
     *          On entry, the triangular factor U or L from the Cholesky
     *          factorization A = U**T*U or A = L*L**T, as computed by
     *          DPOTRF.
     *          On exit, the upper or lower triangle of the (symmetric)
     *          inverse of A, overwriting the input factor U or L.
     *
     *  LDA     (input) INTEGER
     *          The leading dimension of the array A.  LDA >= max(1,N).
     *
     *  INFO    (output) INTEGER
     *          = 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.
     *
