在 MATLAB Online 中打开

You forgot to attach your m-file. Most likely, you wrote a script, say test.m, and inside there it starts off with a script and then you include the function below it in the same file, like this

clc;
result = myfirst(10,20);
function theSum = myfirst(v,w)
  theSum = v+w;

To fix, declare test a function also so that you have two functions in the file, not a script and a function, like

function test()
  clc;
  myfirst(10,20);
function theSum = myfirst(v,w)
  theSum = v+w;

If this does not fix your problem, then attach your m-file(s).

I got it, I am very new to this and my homework tutorial is pretty bland. I understand now about the m files and you have to create an m file and so on. Thanks for the help! Much appreciated!

You marked it as accepted, but the comment before last you said "it still won't work" and you didn't attach your m-file like I suggested, so is everything working or not? Again, if you need more help, attach your m-file.
