You mean you have 100 individually named structs or you have 1 struct with those 100 fields? If the latter than your plot instruction obviously needs to include the name of the struct itself. If the former why on earth would you do that rather than just create an array of 100 structs?!

I solve it in this manner as you mentioned:
for k=1:100
L=struct2cell(load(['data_' num2str(k) '.mat']))
aa(:,k)=L{1}.a;
bb(:,k)=L{1}.b;
end
thank you

Thanks Stephen! Yes it is requirde and it does work for my case. I have diffrent struct with diffrent names. So i tried to collect the interessting data in an Array.

Aha... so someone put meta-data into structure names, and now this makes the saved data harder to process. Not very surprising. This is why meta-data does not belong in variable names:
