Details:

Having the following classdef in file testclass.m:


classdef testclass
        properties
                testnumber = 0;
        endproperties
        
        methods
                function p = testclass()
                        p.testnumber = 1337;
                endfunction
                
                function result = getNumber(obj)
                        result = obj.testnumber;
                endfunction
        endmethods
endclassdef


The ismethod() function (if I understood it correctly from the matlab
documentation) should return true, if the class or object given as first
parameter has a public method with the name given as second parameter. So the
following calls to ismethod should return true:


testinstance = testclass();
ismethod(testinstance, 'getNumber')
ismethod('testclass', 'getNumber')


But they return false.
