Duplicating part of a matrix

Say I have a row vector, and I want to make another vector of all the values in the other one greater than some threshold. I can probably do this with an if inside a for loop, or something like that, but is there a specific command for this?

there is no a specific command for a general question, can you post an example?

A = [1 2 3 4 5 6 7];
B = A(A>4);

Sweet! Just what I hoped for.
