IMSL Name:  CAXPY (Single precision version)
 
Revised:    August 9, 1986
 
Purpose:    Compute the scalar times a vector plus a vector,
            y = ax + y, all complex.
 
Usage:      CALL CAXPY (N, CA, CX, INCX, CY, INCY)
 
Arguments:
   N      - Length of vectors X and Y.  (Input)
   CA     - Complex scalar.  (Input)
   CX     - Complex vector of length MAX(N*IABS(INCX),1).  (Input)
   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.
   CY     - Complex vector of length MAX(N*IABS(INCY),1).
               (Input/Output)
            CAXPY replaces Y(I) with CA*X(I) + Y(I) for I = 1,...N.
            X(I) and Y(I) refer to specific elements of CX and CY.
   INCY   - Displacement between elements of CY.  (Input)
            Y(I) is defined to be
               CY(1+(I-1)*INCY) if INCY.GE.0  or
               CY(1+(I-N)*INCY) if INCY.LT.0.
