Question

I want to evaluate the difference (susbtraction) between all elements in a vector and have the maximum as a result.

For example with

[1 3 7]

the diffs are 2, 4 and 6, so that the result should be 6.

How can I do that with matlab in a clever way?

Answer 1

The maximum difference between any two elements in an array is the difference between the maximum and the minimum value of the array:

x = [1 3 7];
maxDifference = max(x) - min(x)
maxDifference =
     6
