Findduplicates UN + UNC + TOL

Hi,
The documentation states that UN and UNC flags are not compatible with the RN flag which is fine. I am trying to also incorporate the TOL flag but getting an error so I am guessing it is incompatible (partly because it says so). Is it possible to have TOL and UN/UNC combined? I am using IP9.
I am exploring work arounds using histograms.

It's the /UN flag that doesn't like /TOL. I can see an argument that if you allow a range of values to count as duplicates, what value do you put in the /UN wave?

Hi,
My objective is get both values within a tolerance as well as the number of points within that group. A histogram has some hard boundaries which I would like to avoid. I have done a test with
Input wave is 655400 points of values between 0 and 100.
The test wave is showing 25 non-dupe values and the text wave has 246 points so they do line up.
Fail back is to write a function to first do the findduplicates with tolerance and then loop through the original wave testing each found value. Just hoping to use an existing function.

Andy,
The /UN flag is not going to have tolerance because that, by definition, implies it is not an exact duplicate. I think you can get the results that you want in one line of matrixop involving the within() function.
