Function f=fact(num) If num<0 f='no factor'; else if num==0 f=1; Else f=1; While num>=1 f=f*num; num=num-1; End End End

No, there are numerous syntax errors there, as the lint in the code editor will point out to you with red lines or red error messages.

For some of them: function, if, while, and else do not have a capital letter at the start of them. And "Else if" is one lower case word "elseif".

The indenting is also messed up. In the MATLAB code editor you can type control a (to select All text) and then control i (to properly indent all the code). To put it here, paste the code here, highlight it, and then (not before) click the {} Code button:

That's why I told you how to fix it, and the last link I gave basically tells you the same thing, but also has other good info. Give it a try - it's a good thing to learn.
