<H4>Routine</H4>
<DL>
<DT>
void VRfSubt (const float x1[], const float x2[], float y[], int N)
</DL>
<H4>Purpose</H4>
<DL>
<DT>
Element-by-element subtraction of two float arrays
</DL>
<H4>Description</H4>
This routine calculates the difference of corresponding elements of two float
arrays,
<PRE>
y[i] = x1[i] - x2[i], 0 <= i < N.
</PRE>
<H4>Parameters</H4>
<DL>
<DT>
-> const float x1[]
<DD>
Input array (N elements)
<DT>
-> const float x2[]
<DD>
Input array (N elements)
<DT>
<- float y[]
<DD>
Output array (N elements). The output array can be the same as either
of the input arrays.
<DT>
-> int N
<DD>
Number of elements in the arrays (may be zero)
</DL>
