Routine

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

Purpose

Find the symmetric or anti-symmetric part of a vector

Description

  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).
