Bug introduced in 11.1.0 and persisting through 11.1.1
In V11.1,
NSolve[BesselJ[0, x] == 0 && 0 < x < 20, x]
returns no solutions:
But in V11.0 (and earlier), it returns all solutions:
Is there anyway to get NSolve
to solve this equation in V11.1?
(Interestingly, Solve[BesselJ[0, x] == 0 && 0 < x < 20, x]
works in both, but I was particularly interested NSolve
, since I was wanting to compare it with other numerical methods.)
NSolve[]
works fine. $\endgroup$ – J. M.'s ennui♦ Apr 18 '17 at 13:54NSolve[BesselJ[0, x] == 0 && 0 < x < 20, x, Abracadabra] // Quiet
