Maybe something like this is what you want:
Dist_type = {'Kernel', 'Gamma', 'Normal','Weibull'};
for j = 1 : numel(Dist_type)
% Make two tables of the values in the jth column of Testdata that are
% within the two ranges:
% (Note that the first range as initially written would always contain
% no data, so I switched it around.)
t1 = table(Testdata(Testdata(:,j) > 11.19 & Testdata(:,j) < 11.23,j));
t2 = table(Testdata(Testdata(:,j) > 11.28 & Testdata(:,j) < 11.33,j));
% Do something with the tables
end
If you really want to go row-by-row, you can do that by adding a second nested for loop, but the code was already essentially operating on all rows at once.
