I have a 60032x1 matrix. With the data I have, I made a histogram. I want the three most repeating values from it. I want the bin centres so that i can plot another graph with it.
Can someone help me with this? Thanks in advance :)

a = [randn(10000,1)-5; randn(10000,1); randn(10000,1)+5];
histogram(a)
[y,edges] = histcounts(a);
% Use the center of edges as x-axis
x = (edges(1:end-1) + edges(2:end))/2; % bin centre
figure
plot(x, y)
[pks,locs] = findpeaks(y, x)
hold on
plot(locs, pks, '*')
