VRfSubt


Routine

void VRfSubt (const float x1[], const float x2[], float y[], int N)

Purpose

Element-by-element subtraction of two float arrays

Description

This routine calculates the difference of corresponding elements of two float arrays,
  y[i] = x1[i] - x2[i],  0 <= i < N.

Parameters

-> const float x1[]
Input array (N elements)
-> const float x2[]
Input array (N elements)
<- float y[]
Output array (N elements). The output array can be the same as either of the input arrays.
-> int N
Number of elements in the arrays (may be zero)
