Unique function for rows with switched elements
Version 1.0.1 (1,68 KB) von
Sim
Find unique rows in a 2-element matrix, when rows have switched elements. E.g. when row "1 5" and row "5 1" are both present.
This Matlab function provides a way to find:
- unique 2-element rows, when rows have switched elements ("u"), i.e., for example, both rows "1 5" and "5 1" are present in the input matrix,
- rows with switched elements ("s"), and
- indices of rows with switched elements ("is").
Note: this function is designed ONLY for 2-column matrices as input.
