MATLAB: Outputting numbers not selected in using “randperm” command

random permutation of numbers

I have a row which contains 93 numbers ranging from 1 to 116. The numbers in the rows are randomly selected using "randperm" command. Now, I want to output the numbers that are not selected. How do we do that?

Best Answer

Select_How_Many = 42;
Num_in_Row = length(row);
selection_index = randperm(Num_in_Row, Select_How_Many);
unselection_index = setdiff(1:Num_in_Row, selection_index);
selected_values = row(selection_index);
unselected_values = row(unselection_index);
