p_save Change Size on Every Loop Iteration

Hello, I wrote this code in Matlab and it sais that p_save change size on every loop iteration (p_save = [p_save p]), so I would like to improve it.
p_save = [];
syms ps
q = linspace(eps,150,60);
for i = 1 : length(q)
A_qs_flut = ps^2*q(i);
DA = det(A_qs_flut);
characteristic_equation = sym2poly(DA);
p = roots(characteristic_equation);
p_save = [p_save p];
end
I know that I can create an array with the right size and then substitute inside the values.
p_save = ones (4, length(q))
My question is: how can I substitute in a smart and fast way the p values inside the p_save array.
Thanks in advance.

p_save(:,i)=p

Yes. You would need declare p_save = ones (4, 2*length(q))
p_save(:,2*i-1)=p
p_save(:,2*i)=DA
