***PURPOSE Multiply a vector by a constant.
***CATEGORY D1A6
***TYPE DOUBLE PRECISION (SSCAL-S, DSCAL-D, CSCAL-C)
***KEYWORDS BLAS, LINEAR ALGEBRA, SCALE, VECTOR

***DESCRIPTION
B L A S Subprogram
Description of Parameters
--Input--
N number of elements in input vector(s)
DA double precision scale factor
DX double precision vector with N elements
INCX storage spacing between elements of DX
--Output--
DX double precision result (unchanged if N.LE.0)
Replace double precision DX by double precision DA*DX.
For I = 0 to N-1, replace DX(IX+I*INCX) with DA * DX(IX+I*INCX),
where IX = 1 if INCX .GE. 0, else IX = 1+(1-N)*INCX.
