26.02.2017 · I have a 1-by-1 struct that possesses 3 fields named B, C, and D. Is there any way to call D by its index (i.e., D is the third field of struct A, so call the third field of struct A without mentioning the field name D) rather than its name (i.e, A.D)?

If you need to use a structure what I found worked very well was to first convert to a cell then you have the best of both worlds. S = struct('A', [1 2], 'B',[3 4 5]); S_Cell = struct2cell(S); %Then as per gnovice for loopIndex = 1:numel(S_Sell) % Loop over the number of cells array = S{loopIndex}; % Access the contents of each cell %# Do stuff with array end

13.12.2005 · In MATLAB 6.5 (Release 13), we introduced dynamic field references into MATLAB. What are they and why should you use them? In MATLAB, there are 3 basic types of arrays, traditional ones where you index using parentheses () , cell arrays where you can address the contents using curly braces {} , and structures (known in MATLAB as the type struct ) where …
