/**
* Interchanges two vectors.
*
* ## Notes
*
* -   In general, for best performance, especially for large vectors, provide 1-dimensional `ndarrays` whose underlying data type is either `float64` or `float32`.
*
* @param x - first input array
* @param y - second input array
* @throws first argument must be either an array-like object or a 1-dimensional `ndarray`
* @throws second argument must be either an array-like object or a 1-dimensional `ndarray`
* @throws input arrays must be the same length
* @returns `y`
*
* @example
* var x = [ 4.0, 2.0, -3.0, 5.0, -1.0 ];
* var y = [ 2.0, 6.0, -1.0, -4.0, 8.0 ];
*
* gswap( x, y );
* // x => [ 2.0, 6.0, -1.0, -4.0, 8.0 ]
* // y => [ 4.0, 2.0, -3.0, 5.0, -1.0 ]
