zlarscl2.f -


subroutine zlarscl2 (M, N, D, X, LDX)
 
ZLARSCL2 performs reciprocal diagonal scaling on a vector.

ZLARSCL2 performs reciprocal diagonal scaling on a vector.
Purpose:
 ZLARSCL2 performs a reciprocal diagonal scaling on an vector:
   x <-- inv(D) * x
 where the DOUBLE PRECISION diagonal matrix D is stored as a vector.
Eventually to be replaced by BLAS_zge_diag_scale in the new BLAS standard.
Parameters:
M
          M is INTEGER
     The number of rows of D and X. M >= 0.
N
          N is INTEGER
     The number of columns of D and X. N >= 0.
D
          D is DOUBLE PRECISION array, length M
     Diagonal matrix D, stored as a vector of length M.
X
          X is COMPLEX*16 array, dimension (LDX,N)
     On entry, the vector X to be scaled by D.
     On exit, the scaled vector.
LDX
          LDX is INTEGER
     The leading dimension of the vector X. LDX >= 0.
