void cscal( n, a, x, incx )
Integer incx, n;
Complex a;
Complex (*x)[ n ];
void zdscal( n, a, x, incx )
Integer incx, n;
double a;
Complex (*x)[ n ];
void csscal( n, a, x, incx )
Integer incx, n;
float a;
Complex (*x)[ n ];
DESCRIPTION
dscal, sscal, zscal, cscal, zdscal, and csscal scale the vector x of
length n and increment incx by the constant a.
For dscal, sscal, zscal and cscal the constant a is of the same type as
the vector x. zdscal and csscal scale a "complex" vector by "real"
constant.
