}
Computes the dot product of `x` and `y`.

@param {PositiveInteger} N - number of indexed elements
@param {NumericArray} x - first input array
@param {integer} strideX - `x` stride length
@param {NumericArray} y - second input array
@param {integer} strideY - `y` stride length
@returns {number} dot product

@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 ];
var z = gdot( x.length, x, 1, y, 1 );
// returns -5.0
