public class Dormr2

extends 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
 *  =======
 *
 *  DORMR2 overwrites the general real m by n matrix C with
 *
 *        Q * C  if SIDE = 'L' and TRANS = 'N', or
 *
 *        Q'* C  if SIDE = 'L' and TRANS = 'T', or
 *
 *        C * Q  if SIDE = 'R' and TRANS = 'N', or
 *
 *        C * Q' if SIDE = 'R' and TRANS = 'T',
 *
 *  where Q is a real orthogonal matrix defined as the product of k
 *  elementary reflectors
 *
 *        Q = H(1) H(2) . . . H(k)
 *
 *  as returned by DGERQF. Q is of order m if SIDE = 'L' and of order n
 *  if SIDE = 'R'.
 *
 *  Arguments
 *  =========
 *
 *  SIDE    (input) CHARACTER*1
 *          = 'L': apply Q or Q' from the Left
 *          = 'R': apply Q or Q' from the Right
 *
 *  TRANS   (input) CHARACTER*1
 *          = 'N': apply Q  (No transpose)
 *          = 'T': apply Q' (Transpose)
 *
 *  M       (input) INTEGER
 *          The number of rows of the matrix C. M >= 0.
 *
 *  N       (input) INTEGER
 *          The number of columns of the matrix C. N >= 0.
 *
 *  K       (input) INTEGER
 *          The number of elementary reflectors whose product defines
 *          the matrix Q.
 *          If SIDE = 'L', M >= K >= 0;
 *          if SIDE = 'R', N >= K >= 0.
 *
 *  A       (input) DOUBLE PRECISION array, dimension
 *                               (LDA,M) if SIDE = 'L',
 *                               (LDA,N) if SIDE = 'R'
 *          The i-th row must contain the vector which defines the
 *          elementary reflector H(i), for i = 1,2,...,k, as returned by
 *          DGERQF in the last k rows of its array argument A.
 *          A is modified by the routine but restored on exit.
 *
 *  LDA     (input) INTEGER
 *          The leading dimension of the array A. LDA >= max(1,K).
 *
 *  TAU     (input) DOUBLE PRECISION array, dimension (K)
 *          TAU(i) must contain the scalar factor of the elementary
 *          reflector H(i), as returned by DGERQF.
 *
 *  C       (input/output) DOUBLE PRECISION array, dimension (LDC,N)
 *          On entry, the m by n matrix C.
 *          On exit, C is overwritten by Q*C or Q'*C or C*Q' or C*Q.
 *
 *  LDC     (input) INTEGER
 *          The leading dimension of the array C. LDC >= max(1,M).
 *
 *  WORK    (workspace) DOUBLE PRECISION array, dimension
 *                                   (N) if SIDE = 'L',
 *                                   (M) if SIDE = 'R'
 *
 *  INFO    (output) INTEGER
 *          = 0: successful exit
 *          < 0: if INFO = -i, the i-th argument had an illegal value
 *
 *  =====================================================================
