MATLAB: How to set mutually exclusive arguments in matlab

argumentsMATLABmatlab function

How to use the new "arguments" parameter qualifier to control mutually exclusive two(or more) parameters as function inputs?
for example:
function out = twoStats(x,y)
    arguments
        % If you have input x, you cannot input y
         % If you have input y, you cannot input x
    end
end

Best Answer

function out = twoStats(x,y)
    arguments
        x = [];
        y {MustBeExclusive(x,y)} = [];
    end
    % out = ...
end
function MustBeExclusive(varargin)
    if sum(cellfun('isempty',varargin)) ~= 1
        eid = 'XY:NotExclusive';
        msg = 'X and Y must be exclusive.';
        throwAsCaller(MException(eid,msg))
    end
end
