Follow-up Comment #26:

I applied your patch locally and made only some whitespace changes. Please,
see the attached updated patch.

I can confirm that the test case without "byrows" set to true is much faster
now.
Also, the `x = 1:.045:3` seems to be working now.

However, NaN values don't seem to be treated as different values any longer:

>> uniquetol ([-Inf, 1, NaN, Inf, NaN, Inf])
ans =

  -Inf     1   Inf   NaN


In Matlab R2021a:

>> uniquetol ([-Inf, 1, NaN, Inf, NaN, Inf])

ans =

  -Inf     1   Inf   NaN   NaN


Could you please check if it is possible to return all NaNs also with the new
fast path?
