indexing to find elements between 2 values in a matrix

I have created a random 5x5 matrix called M6

i'm trying to using indexing, define an array containing all elements of M6 that are negative or between 29 and 33

clc
clear
 
M6=-10+(33+10)*rand(5)
 

B=(M6<0 & M6>29 & M6<33)

but its just coming up with a 5x5 matrix of 0's
