## VRdCopy

#### Routine

void VRfCopy (const double x[], double y[], int N)

#### Purpose

Copy an array of doubles

#### Description

This routine copys the elements from one double array to another,

      y[i] = x[i],  0 <= i < N.

The copying operation procedes from lowest index to highest index. For this reason, the input and output arrays can only have overlapping storage if the output array starts at a lower address than the input array.

#### Parameters

-> const double x[]
  Array of doubles (N elements)
<- double y[]
  Output array of doubles (N elements)
-> int N
  Number of elements in each array
