Plot struct-data in loop

Hi, i have struct data: data_1, data_2.....data_100 iwant to make the following plot in a loop:

 for k=1:100
plot(data_k.a,data_k.b)
end

how could i do this in matlab?

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

Is the strcut2cell really required? That seems a bit awkward to me.

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:
