<H4>Routine</H4>
<DL>
<DT>
void VRfScale (double a, const float x[], float y[], int N)
</DL>
<H4>Purpose</H4>
<DL>
<DT>
Multiply each element of a float array by a scalar value
</DL>
<H4>Description</H4>
This routine multiplies each element of a float array by a scalar value,
<PRE>
y[i] = a * x[i], 0 <= i < N.
</PRE>
<H4>Parameters</H4>
<DL>
<DT>
-> double a
<DD>
A scalar value
<DT>
-> const float x[]
<DD>
Input array (N elements)
<DT>
<- float y[]
<DD>
Output array (N elements). The output array can be the same as the
input array.
<DT>
-> int N
<DD>
Number of elements in the arrays (may be zero).
