Hi.
I store some data in structure :
H0=struct('h',[0,0],'Q_centroid',[0,0],'Q_action',[.5,.51,.5,.51],'Q_table',[0]);
H1=struct('h',[0,2],'Q_centroid',[5,0],'Q_action',[.5,1,.5,1],'Q_table',[1;2]);
L0=struct('H0',H0,'H1',H1);
L0Names = fieldnames(L0);
n=numel(L0Names);
i=1;
for loopIndex = 1:numel(L0Names)
stuff = L0.(L0Names{loopIndex});
w{i}=stuff;
e(i,:)=w.h;
i=i+1;
end
i want to access h in each H0 and H1 in loop and store them in a matrix 2 by 2 (e=[0 0;0 2]). how can i do this?
i use e(i,:)=w.h but there is an error.
Thanks

You are almost there.
Try this:
H0=struct('h',[0,0],'Q_centroid',[0,0],'Q_action',[.5,.51,.5,.51],'Q_table',[0]);
H1=struct('h',[0,2],'Q_centroid',[5,0],'Q_action',[.5,1,.5,1],'Q_table',[1;2]);
L0=struct('H0',H0,'H1',H1);
L0Names = fieldnames(L0);
n=numel(L0Names);
stuff = nan(numel(L0Names),2); % preallocation
for i = 1:numel(L0Names)
stuff(i,:) = L0.(L0Names{i}).h; % goes like this: L0.H0.h, L0.H1.h,.... etc
end
