MATLAB: How to store each for loop array values in avariable

store for loop values in a variable

Hello,
I would like to store the array values that I got using a for loop in a single variable. This was the code that I used.
function ret=poly_prod(P1,P2)
n=poly_row(P1)
m=poly_row(P2)
a=size(n)
b=size(m)
for n=1:b(2)
ret=P1*P2(n)
end
end
I got an answer like this,
ret =
3 3 -21 -45
ret =
-1 -1 7 15
ret =
2 2 -14 -30
R =
2 2 -14 -30
I am expecting the output to be like R = 3 3 -21 -45 -1 -1 7 15 2 2 -14 -30
Thank you.

ret=[];
for n=1:b(2)
      ret=[ret P1*P2(n)]
end
