Thanks for taking the time to read this. I am working with 5D matrices (in my code resultG, resultX, resultY). These matrices contain 500*500 matrices that are generated 10 times(ntrials) for each value of q and n.
My question is how should I define resultG with indices as my input for function ADMM? I have attached a part of my script.
resultX=zeros(length(n),length(q), ntrials, M, N);
resultY=zeros(length(n),length(q), ntrials, M, N);
for i=1:length(n)
for j=1:length(q)
gamma = 6/((q(j) - p)*n(i));
for k=1:1:ntrials
[X,Y,Q, iter] = ADMM(resultG(i,j,k),c, n(i), gamma,tau, opt_tol, verbose);
resultX(i,j,k, :, :)=X;
resultY(i,j,k, :, :)=Y;

"My question is how should I define resultG with indices as my input for function ADMM"
I understand that resultG is a 5D array but I don't see where that array is created. To answer your question, we'll need to understand the size and shape you expect resultG to be when going into the ADMM() function.
Would the squeeze() function be what you're looking for?

I create that array using the following script. G, X0, and Y0 are all MxN matrices.
resultX0 = zeros(length(n), length(q), ntrials, M, N);
resultY0 = zeros(length(n), length(q), ntrials, M, N);
resultG = zeros(length(n), length(q), ntrials, M, N);
for i=1:length(n)
for j=1:length(q)
for k=1:ntrials
[G,X0,Y0]=matrix_plantsubm(M,N,c,n(i),p,q(j));
resultX0(i,j,k,:,:)=X0;
resultY0(i,j,k,:,:)=Y0;
resultG(i,j,k,:,:)=G;
end
end
end

It's still a little unclear what size and shape you expect resultG(i,j,k) to be going into the ADMM() function but if you expect it to be a matrix, use squeeze().
[X,Y,Q, iter] = ADMM(squeeze(resultG(i,j,k,:,:)),c, n(i), gamma,tau, opt_tol, verbose)
