Simplifiing the MATLAB code

Hi there, I know this is something simple, but I am quite new in matlab and will aprreciate your help with this issue,

I know order of specific events in one dimension matrix:

    e1 = [1,19,24]; % order of specific condition in matrix;
    e2 = [2,8,27];
    e3 = [4,16,23];

I have data with the same event type and I need to change event.type based on information above, so that:

    EEG.event(1,1).type = 1;EEG.event(1,19).type = 1;EEG.event(1,24).type = 1;
    EEG.event(1,2).type = 2;EEG.event(1,8).type = 2;EEG.event(1,27).type = 2;
    EEG.event(1,4).type = 3;EEG.event(1,16).type = 3;EEG.event(1,23).type = 3;

How can I do it in simple way?

Thank you very much for your time and help!

Would you like a for loop? This could be simpler if the e vectors were much long than 3 elements

for k = 1 : length(e1)
    EEG.event(1,e1(k)).type = 1;
    EEG.event(1,e2(k)).type = 2;
    EEG.event(1,e3(k)).type = 3;
end

If e1, e2, and e3 don't all have the same length then you're best off using 3 separate for loops.
