WebSuppose we wish to test whether two vectors are equal. The naive approach, using ==, won’t work. What happened? The key point is that we are dealing with vectorization. Just like almost anything else in R, == is a function. In fact, == is a vectorized function. The expression x == y applies the function == () to the elements of x and y ... WebMar 24, 2015 · Sort and then check if any two consecutive elements are the same: result = any (diff (sort (x))==0); Do all pairwise comparisons manually; remove self-pairs and duplicate pairs; and check if any of the remaining comparisons is true: result = nnz (tril (bsxfun (@eq, x, x.'),-1))>0;
