//This function shifts the series x supplied as input argument by a number of samples d.
//Calling Sequence
//y = fracshift(x, d)
//y = fracshift(x, d, h)
//[y, h] = fracshift(...)
//Parameters 
//x:
//d:
//h:
//Description
//This is an Octave function.
//This function shifts the series x supplied as input argument by a number of samples d. 
//The third parameter is the interpolator, which is designed with a Kaiser-windowed sinecard by default, if not supplied.
//Examples
//fracshift([1,2,3],5)
//ans  =
//    1.    2.    3.
