for i=1:100
    load (['a' num2str(i) '.mat']) 
   end

what schould i write in the same plot to get the plot of all elements in the same plot?

    figure(1)
    for i=1:100
       load (['a' num2str(i) '.mat'])
       plot(a) 
       hold on
    end
    hold off

However the problem is the color: you can try to build a 100x3 matrix containing the values of the colors you want but it is too long plus for a 100 plots you might get colors that are too similar

thanks for the answer. I dont have a as variable, but a1,a2,....a100

You can try

plot(eval(['a' num2str(i) '.mat']));

It is said that eval may give the wrong result sometimes, but it have not happened for me yet. However, if you want to do something else that is more safe you can do

q = load (['a' num2str(i) '.mat'])
qnames = fieldnames(q);
plot(q.(qnames{1}));

or you can search for a replacement for eval.
