How to store index values in the form of arrays using for loop?

Hello Everyone
Can you please tell me how to save indes values of the following code from the for loop?
rng default
M = zeros(randi([3 6]),randi([3 6]))
[u,v] = size(M)
for i = 1:u
for j = 1:v
ind1(i) = i;
ind2(j) = j;
indices = [ind1(i),ind2(j)]
end
end
I want to store the values in the form of two colums and m*n rows.
Thank you

rng default
M = zeros(randi([3 6]),randi([3 6]))
[u,v] = size(M)
inc =1;
for i = 1:u
for j = 1:v
indices(inc,:) = [i ,j];
inc = inc+1;
end
end
or you can use to ind2sub instead of for loop
[x,y]=ind2sub(size(M),1:numel(M));
indices = [y' x'];

Cell array
rng default
M = zeros(randi([3 6]),randi([3 6]))
[u,v] = size(M)
indices=cell(u,v);
for i = 1:u
for j = 1:v
ind1(i) = i;
ind2(j) = j;
indices{i,j}=[ind1(i),ind2(j)];
end
end
