how to sort an array of objects on more than one object parameter

Hi, if I have my class (created in matlab via classdef) containing say three parameters. 1. Sector 2. CalculationSuccess 3) CalculationValue

Is there an easy way I can sort an array of objects of this class on, say, Sector then the CalculationSuccess flag, then the ascending CalculationValue?

The only ways I can think of are long and complicated and in matlab that usually means you're doing something wrong :)
