Hi Thomas,
I understand that you are trying to append struct in a cell array and confused if MATLAB is exhibiting pass by reference. For built-in data types, MATLAB always passes arguments 'by value'. If the input is a handle object, then pass by reference is exhibited. I suggest to pass the buffer as an input argument to the function where depth of an image struct is being read, add the struct to the buffer. Below is an example you can refer to:
buffer={};
for i=1:10
buffer=fillBuffer(buffer);
end
function buffer=fillBuffer(buffer)
for j=1:5
sample_struct.a = randi([10,20],1,1);
sample_struct.b = randi([10,30],1,2);
buffer{end+1}=sample_struct;
end
end
