The function returns [4 6 8]. What I want is that key should be a vector instead of a scalar. As example vec=[15 10 7 8 98 8 3 8] and key=[15 8]. The function should return [1 4 6 8]. How can I change the function file.

What if it was a cellarray it has to search through and find some values?How would the code looklike? Best Regards Hans
