Unique elements of a vector

C++ Prototype

mwArray unique(const mwArray &a);
mwArray unique(const mwArray &A, const mwArray &flag);
mwArray unique(mwArray *index, const mwArray &a);
mwArray unique(mwArray *index, const mwArray &A, 
                const mwArray &flag);
mwArray unique(mwArray *index, mwArray *j, const mwArray &a);
mwArray unique(mwArray *index, mwArray *j, const mwArray &A,
                const mwArray &flag);

C++ Syntax

#include "matlab.hpp"

mwArray a, A;               // Input argument(s)
mwArray index, j;           // Output argument(s) 
mwArray b;                  // Return value

b = unique(a);
b = unique(A,"rows");
b = unique(&index,a);
b = unique(&index,A,"rows");
b = unique(&index,&j,a);
b = unique(&index,&j,A,"rows");

MATLAB Syntax

b = unique(a)
b = unique(A,'rows')
[b,index] = unique(...)
[b,index,j] = unique(...)
