## VRfAdd

#### Routine

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

#### Purpose

Element-by-element sum of two float arrays

#### Description

This routine calculates the sum 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
