1 2 3 4
>> X = X./max(max(X));
0.2500 0.5000 0.7500 1.0000
I understand from the output, but what does "./" means?

the dot means an elementwise operation. See here:

You are dividing X matrix (element-wise) with the element of matrix X having maximum value.
Like in this case, max(X) or max(max(X)) will be 4, and you are going to divide matrix X with that 4, Where 4 will be divided to each element of matrix X in this element-wise division case, So you got the final result,
X= 0.2500 0.5000 0.7500 1.0000
