Quantiles in Matlab -

would there function in matlab, or easy way, generate quantile groups each data point belongs to?

example:

x = [4 0.5 3 5 1.2]; q = quantile(x, 3);  ans =      1.0250    3.0000    4.2500

so see following:

result = [2 1 2 3 1]; % quantile groups

in other words, looking equivalent of thread in matlab

thanks!

you can go through n quantiles in loop , use logical indexing find quantile

n = 3; q = quantile(x,n); y = ones(size(x)); k=2:n     y(x>=q(k)) = k; end
