Display the input options for functions with multiple input arguments

Hi,

I have a function that takes more than one input argument - see my example where there are 2 arguments:

function z = example(x,y)
if nargin == 0
    x = 1;
    y = 1;
elseif nargin == 1
    y = 1;
end
z = x + y;
end

The number of input arguments is flexible from 0 to 2. If there is no argument, put x and y equal to one. If there is only one input argument, let x assume the value of the input argument and y equal one. For both arguments x and y should accept the given value.

Using the function:

nargin

this part works. Now I have the question how I adjust the tooltip when entering so that the user is shown that he has several options. In my case he could call the function in 3 ways and there would be a result. To illustrate my question I have inserted two pictures:

You can see here, as it is at e.g. linprog works - mab gets displayed in the tooltip which variants the function can handle.

For my example, this does not work - here is only one variant that the user gets displayed, although 3 are possible:

From C # I know this procedure as overriding functions, but I know that there is not overriding in matlab in this form. How can I extend this tooltip to show all possible calls to my function as a tooltip?

.

Best regards

I think they did not add this feature for R2018A
