I wrote this simple code
n = [1433;2700;1000000];
s = [1170.98;780.65;390.33];
f= fit(n,s,'power1')
But the error said "invalid expression. check for missing or extra characters"
I'm not very used to Matlab and I absolutely have no idea why this error occurs.
Ofc, I installed Curve Fitting Toolbox

Your code works:
n = [1433;2700;1000000];
s = [1170.98;780.65;390.33];
f= fit(n,s,'power1')
Did you perhaps try to spread that code across multple lines? You might need to use line continuation, if so.

It's difficult to understand what is going on with your code, when it works perfectly fine here.
Do you get this problem from a freshly restarted MATLAB session? How are you calling these lines of code?
Are you sure you have the CF toolbox installed? What do you get if you type
which -all fit
from the command line?
