hai Nasser
I compile the following function, after running successfully.
the problem is when the election "if You Want to calculate the square area of yes = 1 or no = 2" if I choose "1" or "yes" then immediately closed the program, how if you choose "1" or "ye" program back to the initial format and if you select "2" or "no" the application will exit

example function
function square_area
disp('square_area')
l=input('input lenght');
w=input('input width');
disp(['lenght =' num2str(l)])
disp(['Width =' num2str(w)])
a=l*w;
disp(['square_area = ',num2str(a)])
d=input('if you want to calculate the square area yes =1 or no=2');
if d==1
    return
else
    close
end

If I understand you ok, here is one way:
ps. better not to use 'l' are variable name, it looks one the
digit '1'.


-----------------
function square_area

done = false;

while not(done)
    disp('square_area')
    len = input('input lenght');
    w = input('input width');
    
    disp(['lenght =' num2str(len)])
    disp(['Width =' num2str(w)])
    
    a = len*w;
    
    disp(['square_area = ',num2str(a)])
    
    d = input('if you want to calculate the square area yes =1 or no=2');
    
    done = d==2;
end

end
