MATLAB: Sort does not work

Question

Am I missing something very obvious or does the built-in sort function not work as it is supposed to?

Answer 1

Why? for me the indices are correct sorted. The smallest value is found at pos. 3 and the biggest value is found in pos. 4. What is the problem?

Note that the documentation says:

[B, I] = sort(X)

you changed it to:

[I, B] = sort(X)

So maybe what you expect to get is stored in variable I - not B...
