function grev( N, x, strideX ) {
	return ndarray( N, x, strideX, stride2offset( N, strideX ) );
}
Reverses a strided array in-place.

@param {PositiveInteger} N - number of indexed elements
@param {NumericArray} x - input array
@param {integer} strideX - stride length
@returns {NumericArray} input array

@example
var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ];

grev( x.length, x, 1 );
// x => [ -3.0, -1.0, 0.0, 4.0, -5.0, 3.0, 1.0, -2.0 ]
