Do you need all the variables open with every information in the workspace after the plotting? If not, I would do something like this. (Note you dont need to hold on after every plot. When you set hold on, hold is on until you tell it to be off.
A1 = load('A1.mat');
x=A1.Bvalues; %am I correct in assuming your x is the same for every run? Otherwise you must define it within the loop
hold on
for j=1:100
runningfilename=strcat('A',num2str(j),'.mat'); %this should give you 'A1.mat' first run, 'A2.mat' 2nd run, etc.
data=load(runningfilename);
yplot=ata.var_emg_value; %if you dont need any matrix/table with data, just the plots.
%%%% OR
%yplot(:,j)=data.var_emg_value; %you will end up with a yplot matrix of dimension ?x100
%and finally plotting:
plot(x,yplot); %OR plot(x,yplot(:,j)); if you go with the matrix option.
end
Try this - it should produce 100 plots in the same window (notice how hold on is only called once). You can do all sorts of clever things with indexing and for loops, once you know how :)
