It says " Not enough input values" but I can not see which values I have missed? Can you?

Hi, and thanks for your reply. I have tried to call the function in the command window with two input arguments and that works fine. But if I want to be able to run the function (by clicking "Run"), how do I need to change my function to be able to achive this?

"But if I want to be able to run the function (by clicking "Run"), how do I need to change my function to be able to achive this?"

You can either:

write your function to have default values when input arguments are not supplied, or
set up the "Run" button to provide specific input values when you call that function.

Which would you prefer?

Sometimes functions can have default inputs when they are missing from the function-call. Here is an example of how to define default inputs to both of your input variables. The default inputs are defined with the function call is missing the inputs or if the inputs are empty. Sometimes it's good to incude warnings when assigning default inputs so you know when an input was missing. You can remove the warnings in this example, of course.

function [v2, v3] = OrtoVektorFunction(w3, w2)
% Default inputs
if nargin < 1 || isempty(w3)
    w3 = 0; 
    warning('Default input used.')
end
if nargin < 2 || isempty(w2)
    w2 = 1; 
    warning('Default input used.')
end
% Continue with code....
