NAME
CSRSCL - multiplies an n-element complex vector x by the real scalar 1/aSYNOPSIS
- SUBROUTINE CSRSCL(
- N, SA, SX, INCX )
- INTEGER INCX, N
- REAL SA
- COMPLEX SX( * )
PURPOSE
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.ARGUMENTS
- 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
- (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
