Hi, today I have found an error that, using the same code, I haven't found before.
I have a 3D matrix CCC (20x20x3000).
for example (20x20x1) is the one below.
Now I want to find the max value of the matrix doing: max(max(CCC(:,:,1))) and I obtain:
Array indices must be positive integers or logical values.
why?

Probably because you created a variable named "max" earlier in the code, which is now shadowing the max() function.
Incidentally, a better way to find the max over an array is max(CCC(:)) or in recent Matlab max(CCC,[],'all'). These work independently of the dimension of the array, and are more efficient because you only call max() one time.
