public class Dlatzm

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.

 *
 *  Purpose
 *  =======
 *
 *  DLATZM applies a Householder matrix generated by DTZRQF to a matrix.
 *
 *  Let P = I - tau*u*u',   u = ( 1 ),
 *                              ( v )
 *  where v is an (m-1) vector if SIDE = 'L', or a (n-1) vector if
 *  SIDE = 'R'.
 *
 *  If SIDE equals 'L', let
 *         C = [ C1 ] 1
 *             [ C2 ] m-1
 *               n
 *  Then C is overwritten by P*C.
 *
 *  If SIDE equals 'R', let
 *         C = [ C1, C2 ] m
 *                1  n-1
 *  Then C is overwritten by C*P.
 *
 *  Arguments
 *  =========
 *
 *  SIDE    (input) CHARACTER*1
 *          = 'L': form P * C
 *          = 'R': form C * P
 *
 *  M       (input) INTEGER
 *          The number of rows of the matrix C.
 *
 *  N       (input) INTEGER
 *          The number of columns of the matrix C.
 *
 *  V       (input) DOUBLE PRECISION array, dimension
 *                  (1 + (M-1)*abs(INCV)) if SIDE = 'L'
 *                  (1 + (N-1)*abs(INCV)) if SIDE = 'R'
 *          The vector v in the representation of P. V is not used
 *          if TAU = 0.
 *
 *  INCV    (input) INTEGER
 *          The increment between elements of v. INCV <> 0
 *
 *  TAU     (input) DOUBLE PRECISION
 *          The value tau in the representation of P.
 *
 *  C1      (input/output) DOUBLE PRECISION array, dimension
 *                         (LDC,N) if SIDE = 'L'
 *                         (M,1)   if SIDE = 'R'
 *          On entry, the n-vector C1 if SIDE = 'L', or the m-vector C1
 *          if SIDE = 'R'.
 *
 *          On exit, the first row of P*C if SIDE = 'L', or the first
 *          column of C*P if SIDE = 'R'.
 *
 *  C2      (input/output) DOUBLE PRECISION array, dimension
 *                         (LDC, N)   if SIDE = 'L'
 *                         (LDC, N-1) if SIDE = 'R'
 *          On entry, the (m - 1) x n matrix C2 if SIDE = 'L', or the
 *          m x (n - 1) matrix C2 if SIDE = 'R'.
 *
 *          On exit, rows 2:m of P*C if SIDE = 'L', or columns 2:m of C*P
 *          if SIDE = 'R'.
 *
 *  LDC     (input) INTEGER
 *          The leading dimension of the arrays C1 and C2. LDC >= (1,M).
 *
 *  WORK    (workspace) DOUBLE PRECISION array, dimension
 *                      (N) if SIDE = 'L'
 *                      (M) if SIDE = 'R'
