Hi! I have a function and I want to display the max of two scores. For example, if A=5 and B=9 and C is the max, I want C to reply that B is the greater value. How do I do this? Thanks in advance.

How can C, which will equal 9, reply anything? A simple number can't return anything. I assume you want the function to return the name of the biggest variable, like
A = 5;
B = 9;
varName = myFunction(A, B) % Should return a string 'B' in this case for varName.
message = sprintf('%s is the max', varName);
uiwait(helpdlg(message)));
And myFunction would be something like
function letter = myFunction(v1, v2)
if v1 > v2
etc......
And what you'd see is a popup message box with the message "B is the max". Right? I think Walter showed a way, a few months ago, where the function myFunction() could find out the name of the variable name in the calling routine but I don't remember what it was. The function was called something like invarname() or varnames() or varinputname() or something - I don't remember and can't find it now. So like that function would return "B" because it somehow knew that v2 in the function definition was really called B in the calling routine. Perhaps Walter will remind me.

Thanks Walter! Then this seems to work:
function test()
A = 5;
B = 9;
varName = myFunction(A, B) % Should return a string 'B' in this case for varName.
message = sprintf('%s is the greater value', varName);
uiwait(helpdlg(message));
end
function letter = myFunction(v1, v2)
if v1 > v2
letter = inputname(1);
else
letter = inputname(2);
end
end
It pops up a message box that says "B is the greater value" just like you asked for.
