How can ı call this void function from another file.I could not do it

function [] = palindromeprime(n)
reverse = 0;
new = n;
prime = n;
x = true;
   while new > 0
     t = mod(new,10);
     reverse = 10*reverse+t;
     new= (new-t)/10;
   end
   
for i = 2:(prime - 1)
  if mod(prime,i) == 0
    x = false;
    break;
 end
 end

if(n == reverse && x == true)
fprintf("This is a palindrome prime number");
else 
fprintf("This is NOT a palindrome prime number");
end

Just like any other MATLAB function or script...

palindromeprime

from the command line or in a script.

What did you try and what was the error message returned?

It does have to be in a directory on MATLABPATH or in your current working directory to be found...

[Kaan Kara]

palindromeprime(101);

I CALLED FUNCTİON LİKE ABOVE FROM ANOTHER FİLE

HERE IS THE ERROR MESSAGE;

error: 'palindromeprime' undefined near line 2 column 1

error: called from

calis at line 2 column 1

By the way,ı create a file with functions name also

Well, that indicates that the function file name either is misspelled maybe or that the location for it is not in either the working directory or on the MATLABPATH.

What does

which -all palindromeprime

return from the location from which you run the other function?

We can't see that function -- does it, by any chance, change the working directory inside it in order to find some data files? Something like that can break it because move away from the location where the m-file is located.

Without all the information in context, all we can do is guess...
