WebNov 16, 2024 · Ran in: Read about MATLAB matrix indexing. If A is a matrix, you can extract (i,j) element using A (i,j). Also have a look on ind2sub and sub2ind. As you know sub indices here, convert them into global indices using sub2ind and then extract. Theme Copy A = [10 20 30 ; 40 50 60]; B = [3;2] ; idx = sub2ind (size (A), [1;2],B) idx = 2×1 5 4 A (idx) WebMar 21, 2016 · 1 Answer Sorted by: 3 The index is easily obtained with the second output of max. The value can be found from that index using sub2ind or computing the corresponding linear index manually. To return a different index in columns that contain all NaN, use the first output of max to detect that situation and change the result for those columns.
