Output of universal_pertubation()

[shashankvkt]

Thank you very much for the code! Learned a lot from it.

The issue i am facing is that the value of 'v' after being computed is coming out to be NaN.
I am implementing this in Matlab. I have changed the value of
opts.delta = 0.5 and opts.p = 2 (random changes), but in all the cases it outputs value NaN
The new fooling rate comes around 0.99733
Kindly advice.

P.S: To be more specific the output
dr = project_boundary_polyhedron(ddf,ff(idx),Q); is turning out to be zero
