a problem with unique command

Hello all,

I have an mx1 vector A, that is ordered in an ascending manner. I would like to find unique elements of this vector, however, by using "unique" command, I am getting the same output as A. Can anybody tell me how I can resolve this issue? I think it has to be done with matlab precision, but I do not know how to fix it.

Thanks!

Please post a short example showing A and what you want for output, and how you are currently using unique.

when I use "format long"

 A=[1.414213562645795
   1.414213562645985
   1.414213562645985
   1.414213562646871
   1.414213562646871
   1.553773974242559
   1.553773974242559
   1.553773974242644]

and I use unique(A), that's why I get the same output as A, while I need matlab to consider A as

[1.414
 1.414
 1.414
 1.414
 1.414
 1.553
 1.553
 1.553]

so that the output to unique(A) be [1.414 1.553]

Use uniquetol with an appropriate tolerance or discretize your data.
