function gfillBy( N, x, strideX, clbk, thisArg ) {
	return ndarray( N, x, strideX, stride2offset( N, strideX ), clbk, thisArg );
}
Fills a strided array according to a provided callback function.

@param {PositiveInteger} N - number of indexed elements
@param {Collection} x - input array
@param {integer} strideX - stride length
@param {Callback} clbk - callback function
@param {*} [thisArg] - execution context
@returns {Collection} input array

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

function fill() {
    return 5.0;
}

gfillBy( x.length, x, 1, fill );
// x => [ 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0 ]
