How to sort arrays with respect to one of the element in it

Hello everyone, I have

Harmony=7x1 struct with two fields(solution & cost)

NewHarmony=3x1 struct with two fields(solution & cost)

I have combined Harmony and Newharmony and created NHS.

NHS=10x1 struct with two fields(solution & cost)

Now I need to sort the NHS with respect to the costs developed and eliminate the last three elements which will give new set of Harmony with optimised Cost values.

Please help me on this, Thank u

[~, idx] = sort([NHS.cost]);
NHS = NHS(idx(1:end-3));
