How map values of array to 0 and 1

How can i write a function such that it takes an array, and outputs an array of same size with values lying in [0,1] but also that the largest value is mapped to 1, and smallest to 0?

normalized_array = normalize(array,'range',[0 1]);

It's trivial normalisation. Subtract the minimum of your array so the new minimum is 0, then divide by the max of that new array so the max becomes 1.
