2-for loop iteration to output a matrix

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]

A=[5 10 15 45]; %changing variables in the code
B=[2 4]; %another changing variable for iteration

D=A+B'

D = 2×4

@Matt J..thank you for your help.

However, in my real code w & p are just values that varies within the blokcs of codes and functions. I just stated the simple example above for the purposing of getting a guide.

The problem I am having is properly storing the outputs after each round of iteration.

Any further help will be appreciated.

It would probably require an example closer to what you're really doing.

The code looks like this.

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]

[Matt J]

A=[5 10 15 45] %changing variables in the code
B=[2 4] %another changing variable for iteration

Na=numel(A); Nb=numel(B);

D=nan(Nb,Na); %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:Na
    w=A(i);
    for j=1:Nb
        p=B(j);
        num=4;
        mix=2;
        [ar, A_d, pha, ata] = GmmClas(B, num, mix); %GmmClas
        
        D(j,i)= gamu(ar, A_d, pha, A); %gamu is a function
    
    end    
end

Thank you @Matt J. The above works perfectly. I appreciate.
