MATLAB: How to limit the function nchoosek(0:256,4) values to some fixed number, for example first 500 combinations statistics How to limit the function nchoosek(0:256,4) values to some fixed number, for example first 500 combinations? Best Answer Something like this, perhapsn=4;while nchoosek(n,4)<500 n=n+1;endidx=nchoosek(1:n,4);list=0:256;result=list(idx(1:500,:)), Related SolutionsMATLAB: How to set pixel values in 100*100 matrix Try something like thisimg = zeros(100, 'uint8');idx_all = 1:numel(img);idxs = cell(1,3);for i = 1:numel(idxs)-1 idx_temp = randperm(numel(idx_all), round(numel(img)/3)); idxs{i} = idx_all(idx_temp); idx_all(idx_temp) = [];endidxs{end} = idx_all;img(idxs{1}) = 50;img(idxs{2}) = 100;img(idxs{3}) = 200; MATLAB: Nchoosek help Hi Sean, 4 people in a line is just factorial(4). nchoosek assumes you are interested in how many ways you can choose a number of objects out of set where order is not important. Note that arrangement in a circle is different.Wayne Related QuestionGenerate Only a Specific Number of CombinationsNchoosek with multiple arraysRecurring Sequences of NumbersNchoosek – non consecutive numbers
