function y = wrev(x)


    // Reverses order of elements of input vector
// Calling Sequence
//	[y]=wrev(x)
// Parameters
//	x: Input vector of string, real or complex values
// Description
//	This is an Octave function which is built in scilab.
//	This function reverses the order of elements of the input vector x.
// Examples
// 1.	wrev([1 2 3])
//	ans= 3  2  1
// 2.	wrev(['a','b','c'])
//	ans= cba
