multiplies an n-element complex vector x by the real scalar 1/a
- SUBROUTINE CSRSCL(
N, SA, SX, INCX )
SX( * )
CSRSCL 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.
- N (input) INTEGER
The number of components of the vector x.
- SA (input) REAL
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 array, dimension
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
