Hi,

I have a method which calls an external script. Example.

../../script.m:

ret = 1000;

The method looks as follows:

methods
  function value = CalculateEntry(this)
    run('../../script.m');
    value = ret;
  end
end

However, I get

??? Error using ==> CalculateEntry
Output argument "value" (and maybe others) not assigned during call to
...

When I debug the program I see that script.m is executed and "ret" is assigned. However, when "run" returns to "CalculateEntry", "ret" is suddenly NaN.

How to fix this?

Why not convert the script into a function. It'll probably solve your problem and would be cleaner anyway as it's then clear what the inputs and outputs are
