I have a Matrix, M. Any row in M contain 1’s and NaN’s. For row 20, for example, I can find the ids of all columns that do not contain NaN: idfocus = findall(x->~isnan(x),A[20,:]) I am now interested in finding all (if any) rows above 20 (again, just for example) that contain exactly the same id…

Finding all rows that are the same as a "focus" row

Perhaps provide an MWE that generates typical data, so that people can benchmark.
