3 maximum values in a matrix

Hello friends,

I would like to ask for some help, if possible.

I have a matrix :

A = [ 12 45 6 89 55]

How can I get an output that returns the 3 values that are the highest such that my answer would be:

result = [0 45 0 89 55]

please assist if you can.

take care

Asorted = sort(A(:),'descend');
result = Asorted(1:3);

Does this work?

[o1,o2] = sort(A);
A(o2(1:end-3))=0
