Thread Subject: MATLAB matrix help

I am supposed to create a 10x10 matrix an then Extract all 30<=aij<=50 in a vector b....that is find all elements that are between 30 and 50 and put them in a vector b.

I started like this below but it doesn't find the elements between 30 and 50.

A=100*rand(10);
A=fix(A)
x=find(30<=A<=50)

use the logical operator &

q = 30 <= A & A <= 50
