## VRdSymPart

#### Routine

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

#### Purpose

Find the symmetric or anti-symmetric part of a vector

#### Description

This routine creates an output vector which is the symmetric or anti-symmetric part of the input vector,

      y[i] = 0.5 (x[i] +/- x[N-i-1]),  0 <= i < N.

#### Parameters

-> int Sym
  Symmetry flag, +1 or symmetric and -1 for anti-symmetric
-> const double x[]
  Input array (N elements)
<- double y[]
  Output array (N elements). The output array can be the same as the input array.
-> int N
  Number of elements in the arrays (may be zero).
