Details:

When using ~ as the optional 3rd output argument in the unique function the
ismember function using the optional 'rows' argument causes the error:


error: ismember: A(I): index out of bounds; value 1 out of bound 0
error: called from:
error:  
C:\Octave\Octave3.6.1_gcc4.6.2\Octave3.6.1_gcc4.6.2\share\octave\3.6.1\m\set\ismember.m
at line 124, column 10
error:   H:\code\bugTesting.m at line 6, column 6


The error can be reproduced using the code


clear all;
ism1 = ismember([1 2],[1 2;3 4;5 6],'rows')
[a,b,~] = unique({'1','2','3','2','1','6','4'});
ism2 = ismember([1 2],[1 2;3 4;5 6],'rows')
