Okay, I have 4 structs.
CriticalCutAuto %(1x1 with 4 fields called A;B;C;D)
CriticalCutHuman %(1x1 with 4 fields called A;B;C;D)
CriticalFolAuto %(1x13 with 4 fields called A;B;C;D)
CricticalFolHuman %(1x9 with 4 fields called A;B;C;D)
There are 2 categories (Cut Situations and Follow Situations) with 2 subparts of data (Human and Auto). In my current structs, say in CritFolAuto, you can scroll over the box in field A row 1, and click to see the data, which is a 1x100 double.
What I want to be able to do is click on the name AllSituations in the workspace, and a 1x2 struct appears that says 'Follow' and 'Cut'. I then want to be able to CLICK on either of those two files to see another 1x2 struct with 'Human' and 'Auto'. When I CLICK on one of those two, I would like to see the original structs for CriticalCutHuman and the rest in their respective spots, so when I go into that data I can see the four fields A;B;C;D and the data that lies inside of them.
I thought I could call each struct with writing the name and '= []' to call it but I think that is wrong:
function [ AllSituations] = CritSituations( AutomatedData, HumanData )
CritSituations = [];
CriticalCutAuto= [] ;
CriticalCutHuman= [] ;
CriticalFolAuto= [] ;
CriticalFolHuman= [] ;
AllSituations(1).Follow = CriticalFolHuman;
AllSituations(1).Follow = CriticalFolAuto;
AllSituations(2).Cut = CriticalCutHuman;
AllSituations(2).Cut = CriticalCutAuto;
AllSituations = ans
%Critical_Situations = struct('Following Situations', {CriticalFolAuto, CriticalFolHuman}, 'Cut Situations', {CriticalCutAuto, CriticalCutHuman});
end
I also tried the silenced line but that did not work at all.

"Structs are kind of cell arrays"
I think it would be more useful to explain that both cell arrays and structures are different types of Containers (as structures are not really a kind of cell array).

@Stephen: You are right, this was a lazy formulation. In the MEX level structs and cells are very similar and the struct2cell conversion is really fast in consequence. But to see both as containers is more useful. I only wanted to encourage Miranda to get familiar with structs.

% Function to merge structures
function mergedStruct = mergeStructures(struct1, struct2)
% Merge the fields of the two structures
fields1 = fieldnames(struct1);
fields2 = fieldnames(struct2);
for j = 1:length(fields2)
if isfield(struct1, fields2{j})
% Field name already exists in struct1, rename it in struct2
field2new = [fields2{j} '_folder2']; % Or any unique identifier
struct2.(field2new) = struct2.(fields2{j});
struct2 = rmfield(struct2, fields2{j});
end
end
% Merge the structures
mergedStruct = struct1;
mergedStruct = cat(1, mergedStruct, struct2);
end
