Dear all,
I have encountered the problem that restricting domains in NSolve does not work.
I get the same results for NSolve[x^5 - 2 x + 3 == 0, x, Reals] as with NSolve[x^5 - 2 x + 3 == 0, x], namely {{x -> -1.42361}, {x -> -0.246729 - 1.32082 I}, {x -> -0.246729 +
1.32082 I}, {x -> 0.958532 - 0.498428 I}, {x ->
0.958532 + 0.498428 I}}
I.e. Mathematica actually does not apply the restriction.
Does anyone have a solution for this? Do I have to adjust the settings somewhere?
many thanks in advance
Niels
