UNIQUEWITHEQUALNANS
UNIQUEWITHEQUALNANS - Set unique, treating NaNs as equal
B = UNIQUEWITHEQUALNANS(A) for the array A returns the same values as in A
but with no repetitions. B will also be sorted (NaNs as last).
UNIQUEWITHEQUALNANS(A,'rows') for the matrix A returns the unique rows
of A, treating NaNs as equal.
[B,I,J] = UNIQUEWITHEQUALNANS(...) also returns index vectors I and J such
that B = A(I) and A = B(J) (or B = A(I,:) and A = B(J,:)).
[B,I,J] = UNIQUEWITHEQUALNANS(...,'first') returns the vector I to
index the first occurrence of each unique value in A.
UNIQUEWITHEQUALNANS(...,'last'), the default, returns the vector I to
index the last occurrence.
Example:
A = [1 2 NaN ; 1 2 NaN ; 1 2 NaN] ;
unique(A,'rows')
% -> [1 2 NaN ; 1 2 NaN ; 1 2 NaN] ;
uniquewithequalnans(A,'rows')
%-> [1 2 NaN]
For a cell array of strings, this function behaves exactly like UNIQUE.
