clear all
Q=[1 2 3 10 30 -5]
Q = 1×6
     1     2     3    10    30    -5
%insert to the begining of Q
v=100;
Q=[v Q]
Q = 1×7
   100     1     2     3    10    30    -5
%retrieve from the end 
w=Q(end)
w = -5
Q(end)=[]
Q = 1×6
   100     1     2     3    10    30
%As a side note, you can remove any element of Q by setting that element to [], the example below removes the third element 
Q(3)=[]
Q = 1×5
   100     1     3    10    30
