Wrapper function exposing the C API to JavaScript.

@private
@param {integer} N - number of indexed elements
@param {string} dtypeX - `x` data type
@param {Float64Array} x - input array
@param {integer} strideX - `x` stride length
@param {string} dtypeY - `y` data type
@param {Float64Array} y - input array
@param {integer} strideY - `y` stride length
@param {string} dtypeZ - `z` data type
@param {Float64Array} z - destination array
@param {integer} strideZ - `z` stride length
@returns {Float64Array} `z`

@example
var Float64Array = require( '@stdlib/array/float64' );

var x = new Float64Array( 10 );
var y = new Float64Array( x.length );
var z = new Float64Array( x.length );

wrapper( x.length, 'float64', x, 1, 'float64', y, 1, 'float64', z, 1 );
