08 Apr 2009	Determine and count unique values of an array Very fast function to determine and count unique values of numeric, logical, char, cell arrays. Author: Anthony Kendall	it would be nice to extend this to the n-d case, or at least the 2-d case, i.e., find and list unique pairs? x = [1 2; 1 3; 1 2]; then, uniques = [1 2], [1 3]; and, numuniques = [2 1]; thanks

09 Dec 2011	Determine and count unique values of an array Very fast function to determine and count unique values of numeric, logical, char, cell arrays.	Daniel	I haven't actually tried this yet, but how about using the 'sparse' parameter in accumarray? And why not add a 'dim' parameter to your function...I think it's still possible to do this with accumarray.	Comment only
30 Nov 2011	Determine and count unique values of an array Very fast function to determine and count unique values of numeric, logical, char, cell arrays.	Jhay	How to count elements in a row? For Example: [0 0 0 1 1 1 1 0 0 0 1 1 0 1 ] I need to find the position of 1's in a row and count it seperately. Can some1 suggest me solution?	5
16 Feb 2011	Determine and count unique values of an array Very fast function to determine and count unique values of numeric, logical, char, cell arrays.	Tyson	I was wondering if the code could be modified to accept a 'rows' option, like the unique script? I have x,y,z data that can have more than one column identical. Thanks!	Comment only
11 Sep 2010	Determine and count unique values of an array Very fast function to determine and count unique values of numeric, logical, char, cell arrays.	Alexander	Thanks. Nice code. Saves a lot of time over "unique" in counting unique integer values from a relatively large matrix. I didn't try it on integer values.	Comment only
05 Aug 2010	Determine and count unique values of an array Very fast function to determine and count unique values of numeric, logical, char, cell arrays.	Warwick	This is a useful script for me. Just what I needed at the time.	4
