Storing Matrices from a for loop

Hello everyone,
I want to multiply a matrix with a vector, in a for loop. In this case q is a continuous variable.
for q = 0:2:8;
B = [q, sin(q) ;
cos(q), 3*q ;
q, cos(q)]
h = [q; sin(q); 4]
A = B.' * h
end
Now my problem is, that I don't know how to store the result of B, h and A of each loop.
Or is there another solution without a for loop to fill the matrix B with each step? That would be easier for my code.
Best regards

One option is to use an index to loop over the values, like this. You can than directly use that index to create a cell array to store the individual matrices A B and h. Like this
Qlist = 0:2:8
for k = 1:numel(Qlist)
q = Qlist(k) ;
B{k} = [q, sin(q) ;
cos(q), 3*q ;
q, cos(q)]
h{k} = [q; sin(q); 4]
A{k} = B{k}.' * h{k}
end
