MATLAB: Creating an array of arrays

Question

I am trying to generalize creating a 2×2 diagonal array using a for loop.

q = [0.2 0.4]; %2 possible values for process noise variance

Qc1 = diag([q(1) q(1)]); %-> 2×2 matrix

Qc2 = diag([q(2) q(2)]); % -> another 2×2 matrix

Qcm = ???

for i=1:length(q)

Qcm(i) = diag([q(i) q(i)]);

end

My question is what is the correct way to initialize Qcm?

Answer 1

Use a structure array. Doh!

I'll give myself qudos
