How do I call the built-in disp function after I have overloaded it in a different class?

Hi, I have two classes PermutationKey and Attack, within both I am overloading the disp function, yet in writing the disp function for Attack and calling

disp(['Key: ' atk.key]);

disp(['Current decrypted ciphertext: ' start]);

it chooses to call the disp function from the class PermutationKey

function disp(key)

disp(char(key.perm + 64));

end

rather than the built-in disp.

Anyone know a remedy for this situation as I simply wish to use the built-in disp function to print to the console the text provided? Thanks

When you concatenate a char vector and an instance of your PermutationKey class, does that return an instance of the PermutationKey class? What does this return?

class(['Key: ' atk.key])

Maybe explicitly convert the key to a character array?

disp(['Key: ' char(atk.key)])
