How to calculate hurst index in matrix data?

Hello everyone,

I have temperature data in matrix (360x720x120), here 120 is temperature data in 120months. I tried to run the code using hurst function using following link:

https://ch.mathworks.com/matlabcentral/fileexchange/70192-hurst-exponent?s_tid=srchtitle

It is showing some error; Error: Invalid text character. Check for unsupported symbol, invisible character, or pasting of non-ASCII characters.

How to ractify this error? I want the final outcome (map) as 360x720.

Please help me solve this. I will be thankful.

% I have tried to run the code in this way
for y=1:360,
   for x=1:720,
        for i=1:120,
            A(i)= temperature_data(y,x,i);
            H = hurst(A);
        end;                                                            `
      map(y,x)=H; %final outcome
    end;
end;

Notice this line (the end; corresponding to the for i=1:120):

end;                                                            `

There is a bunch of white space and a '`' character after the end;. Delete that stuff and see if it works.
