Have you tried this, Sara?
d = max(2,3,4)
According to the help text this fails.

How would you find the maximum of two variables?
docserach maximum
Then if you have the maximum of two variables, you can compare it to the third one.

In general, for A, B, and C being numerical arrays of any size (possibly different than each other):
% Define 3 double matrixes of different sizes
A = rand(3);
B = rand(4);
C = rand(5);
% Now get the max overall
D = max([A(:), B(:), C(:)]) % Note use of (:) to turn arrays into vectors.
If they're cell arrays or structures though, let us know because that would be different.

If A, B, C hav different sizes, [A(:), B(:), C(:)] fails. But [A(:); B(:); C(:)] with the semicolons for vertical concatenation works.

if it is vectors of different sizes, you would have to do max(max(a),max(b)),max(max(b),max(c)). So, it takes max of the first and second vectors and compares the values, and max of the second and third vectors, then takes the max of those two numbers.

Oh yes, I see. This makes it into one vector then takes the max.
