public class Dlauu2
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.

 *     ..
 *
 *  Purpose
 *  =======
 *
 *  DLAUU2 computes the product U * U' or L' * L, where the triangular
 *  factor U or L is stored in the upper or lower triangular part of
 *  the array A.
 *
 *  If UPLO = 'U' or 'u' then the upper triangle of the result is stored,
 *  overwriting the factor U in A.
 *  If UPLO = 'L' or 'l' then the lower triangle of the result is stored,
 *  overwriting the factor L in A.
 *
 *  This is the unblocked form of the algorithm, calling Level 2 BLAS.
 *
 *  Arguments
 *  =========
 *
 *  UPLO    (input) CHARACTER*1
 *          Specifies whether the triangular factor stored in the array A
 *          is upper or lower triangular:
 *          = 'U':  Upper triangular
 *          = 'L':  Lower triangular
 *
 *  N       (input) INTEGER
 *          The order of the triangular factor U or L.  N >= 0.
 *
 *  A       (input/output) DOUBLE PRECISION array, dimension (LDA,N)
 *          On entry, the triangular factor U or L.
 *          On exit, if UPLO = 'U', the upper triangle of A is
 *          overwritten with the upper triangle of the product U * U';
 *          if UPLO = 'L', the lower triangle of A is overwritten with
 *          the lower triangle of the product L' * L.
 *
 *  LDA     (input) INTEGER
 *          The leading dimension of the array A.  LDA >= max(1,N).
 *
 *  INFO    (output) INTEGER
 *          = 0: successful exit
 *          < 0: if INFO = -k, the k-th argument had an illegal value
