I want to use for-loop for my entire code for simulation.

Specifically, i want to output results of each iteration with 2 for-loops in a matrix. I use the example code to explain my problem

A=[5 10 15 45] %changing variables in the code
B=[2 4] %another changing variable for iteration
D=[] %final output matrix. I want it to be 2 by 4 (such that output of condition B(1,1) & A(:) makes row1 in D...
for i=1:size(A,2)
    w=A(i)
    for j=1:size(B,2)
        p=B(j)
        num=4
        mix=2
        [ar, A_d, pha, ata] = GmmClas(B, num, mix) %GmmClas
        C= gamu(ar, A_d, pha, A) %gamu is a function
    D=[D C] %but I want this output in matrix 92 by4)not as vector 
    end    
end

The entire code is working. I only want to create the for-loop for simulation purpose as it will be tediuos manually changing the varying parameters after each iteration.

D is to be the final output (size -2 by 4) where row1 will be output of when B=2 and A=[5 10 15 45] and row 2 will be B=4 and A=[5 10 15 45]
