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

@private
@param {integer} N - number of indexed elements
@param {Object} x - first input array object
@param {Collection} x.data - first input array data
@param {Array<Function>} x.accessors - first array element accessors
@param {integer} strideX - `x` stride length
@param {NonNegativeInteger} offsetX - starting index for `x`
@param {Object} y - second input array object
@param {Collection} y.data - second input array data
@param {Array<Function>} y.accessors - second array element accessors
@param {integer} strideY - `y` stride length
@param {NonNegativeInteger} offsetY - starting index for `y`
@returns {number} dot product

@example
var toAccessorArray = require( '@stdlib/array/base/to-accessor-array' );
var arraylike2object = require( '@stdlib/array/base/arraylike2object' );

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, arraylike2object( toAccessorArray( x ) ), 1, 0, arraylike2object( toAccessorArray( y ) ), 1, 0 );
// returns -5.0
