DRSCL
November 2006
Purpose
DRSCL multiplies an n-element real 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.
This is done without overflow or underflow as long as

Arguments
| N |
(input) INTEGER
The number of components of the vector x.
|
| SA |
(input) DOUBLE PRECISION
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) DOUBLE PRECISION 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 |
