zsrscl3
Multiplie an n-element complex vector x by the real scalar 1/a
Usage
- SUBROUTINE ZDRSCL(
-
N, SA, SX, INCX )
- INTEGER
-
INCX, N
- DOUBLE
-
PRECISION SA
- COMPLEX*16
-
SX( * )
Purpose
CDRSCL multiplies an n-element complex vector x by the real scalar 1/a. This is done without overflow or underflow as long as the final result x/a does not overflow or underflow.
Arguments
- N (input) INTEGER
-
The number of components of the vector x.
- SA (input) DOUBLE PRECISION
-
The scalar a which is used to divide each component of x. SA must be >= 0, or the subroutine will divide by zero.
- SX (input/output) COMPLEX*16 array, dimension
-
(1+(N-1)*abs(INCX)) The n-element vector x.
- INCX (input) INTEGER
-
The increment between successive values of the vector SX. > 0: SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i), 1< i<= n
< 0: SX(1) = X(n) and SX(1+(i-1)*INCX) = x(n-i+1), 1< i<= n
