How to create new data from old data?

I want to create new data and combine data which has same Alpha with high peak

OldData= [ 0.5 0.6 -0.1 0.2  0.5; ...
           0.2 0.3  0.1 0.7  0.6; ...
           0.7 0.6 -0.2 0.3  0.4];

OldData =

    0.5000    0.6000   -0.1000    0.2000    0.5000    %%%%OldData(1,:) have Alpha=0.6
    0.2000    0.3000    0.1000    0.7000    0.6000    %%%%OldData(2,:) have Alpha=0.2
    0.7000    0.6000   -0.2000    0.3000    0.4000    %%%%OldData(3,:) have Alpha=0.7

If I assume that OldData(1,:) is one signal, and OldData(2,:) and OldData(3,:) are other signals. How can I combine signal which have alphas more than 0.5, which have the higher peak?

for i=1:3
    figure;
    OldData(i,:)

    if Alpha>0.5
        NewData(i,:)=OldData(i,:);
    else 
        NewData(i,:)=0;
    end
end

How I combine signal?

Thank you

Try this:

NewData = zeros(size(OldData));
for k=1:3
    figure;
    OldData(k,:) % Echo to command window.

    if Alpha(k) > 0.5  % Check Alpha for this signal.
          NewData(k,:)=OldData(k,:);
    end
    plot(NewData, 'b*-', 'LineWidth', 2, 'MarkerSize', 12);
end

Of course you must have your Alphas in an array.

Thank you, I can adapt it with my work.
