IMSL Name:  CSUB (Single precision version)
 
Revised:    August 9, 1986
 
Purpose:    Subtract each component of a vector from a scalar,
            x = a - x, all complex.
 
Usage:      CALL CSUB (N, CA, CX, INCX)
 
Arguments:
   N      - Length of vector X.  (Input)
   CA     - Complex scalar which each element of X is subtracted
            from.  (Input)
   CX     - Complex vector of length MAX(N*IABS(INCX),1).
            (Input/Output)
            CSUB replaces X(I) with CA - X(I) for I = 1,...N.
            X(I) refers to a specific element of CX.
   INCX   - Displacement between elements of CX.  (Input)
            X(I) is defined to be
                CX(1+(I-1)*INCX) if INCX.GE.0  or
                CX(1+(I-N)*INCX) if INCX.LT.0.
