How do I get the row numbers of the 'list' where the values are equal to the values of the array 'days'

2 views (last 30 days)
%clear;
%close all;
%clc;
list = [
50 74;
6 34;
147 162;
120 127;
98 127;
120 136;
53 68;
145 166;
95 106;

];
M = sortrows(list);
out = M(sum(squeeze(any(M - permute(M,[3,2,1]) <= 0,2))) == 1:size(list,1),:);
[days] = out(:,1);

Hi Yannick Leroy,
the function ismember() allows to compare matrices with vector elements. The function find() supplies the indices. You don't need to use find() if you can utilize logical indexing.
[ind,~] = find(ismember(list,days)) % find row index only
ind = unique(ind); % remove duplicates
Kind regards,
Robert
