Matlab Error Uint 8

Hello guys, i have some trouble with my code. When i run the code appear some erros:

error: 'steganografie' undefined near line 1, column 1

My code:

function steganografie(imag1, imag2, n)
close all

    
    %size(imag1)
    
   % imag1 = rgb2gray(imag1);
    %imag2= rgb2gray(imag2);
    
    imag1= uint8(imag1); 
    imag2= uint8(imag2);
    
    imag1_modif= floor((imag1/(2^n))) * (2^n)
    imag2_modif= (imag2/(2^(8-n)));
  

    imag_codata =imag1_modif+imag2_modif
    imwrite(imag_codata,'imag1.png')
    imshow(imag_codata),title('Imaginea codata')

    
    figure;
    subplot(1,2,1), subimage(imag1),title('Imaginea in care ascund');
    subplot(1,2,2), subimage(imag2),title('Imaginea pe care o ascund');

end

Can you help me to solve this issue?

You can't run your fcn file: steganografie

without providing the input arguments, viz. imag1, imag2, n

Make sure while calling this fcn file to provide input arguments.

That would not give an error at line 1 column 1.

What would give an error at line 1 column 1 is if there is a different script file that is intended to call steganografie but steganografie is not anywhere on the MATLAB path
