I am very new to MatLab and this is probably a really easy fix but functions are giving me a headache.

global fakt1 fakt2 fakt3
fakt1=2; fakt2=3; fakt3=4;
testfunktion1(10)
function erg=testfunktion1(x)
erg=fakt1*x^3+fakt2*x^2+fakt3*x;
end

I first named the file "testfunktion.m" but then got the Error "Local function name must be different from the script name". After changing the function name and trying to run the script I get the Error

">> testfunktion(10)

Attempt to execute SCRIPT testfunktion as a function: C:\Users\....."

Now I am kind of clueless on what to do.

I am facing an error while executing my script

>> my_model_script

Attempt to execute SCRIPT xlabel as a function:

F:\MathWorks_MATLAB_R2020a_v9.8.0.1323502\toolbox\matlab\graph2d\xlabel.m

Error in my_model_script (line 12)

xlabel('Time (s)');

Don't know what happens it was smooth before. I checked over the location as well but no use

The path looks correct, and that xlabel.m file is a function. Have you by chance named your script 'xlabel'?

What is the result of the following command: which xlabel -all

The issue is that you are treating your script as a function. Functions have inputs, scripts do not.

>> testfunktion(10)

Just call your script without trying to give it an input.

>> testfunktion

As is written, that will create an error about missing variable x. So either turn the entire script into a function, or define x in your script as well.

As far as learning more about MATLAB, I recommend MATLAB Onramp. Also, rather than declare your variables a global, just pass them as inputs to your function. See more here.
