Then Matlab did not find any feasible point ! The exitflag was -2 in this case.
When I use the 'active-set' algorithm and don't specify 'AlwaysHonorConstraints', I find the exitflag to be 0, i.e., the no. of iterations exceeded the max. number.
I don't know if I am making any simple mistake or not :S
Thanks a lot for your help.
