mlfUnique

Unique elements of a vector

C Prototype

mxArray *mlfUnique(mxArray **i, mxArray **j, mxArray *a,
                    mxArray *rows_str);

C Syntax

#include "matlab.h"

mxArray *a, *A;                 /* Input argument(s) */
mxArray *i = NULl, *j = NULL;   /* Optional output argument(s) */
mxArray *b = NULL;              /* Return value */

mlfAssign(&b, mlfUnique(NULL,NULL,a,NULL));
mlfAssign(&b, mlfUnique(NULL,NULL,A,mxCreateString("rows")));
mlfAssign(&b, mlfUnique(&i,&j,a,NULL));
mlfAssign(&b, mlfUnique(&i,&j,A,mxCreateString("rows")));

MATLAB Syntax

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