RE: Oddity with fsolve, nSolve, etc.
I don't understand what you are trying to say, and where you are coming from.

1) Clearly, fsolve and nSolve return an incorrect root (namely 0.), when called with the arguments as I posted in my original posting.

2) Whether the examples show a single solution or not, the fact is that multiple solutions are returned for a particular interval (if they exist), which is actually very valuable and is welcomed, at least in my book.

3) What do you think is the third root of x^3-3*x^2+4 (if you believe 2 is not a double root)?

But if you think that there is no problem, then that is fine with me. I just hope that HP listens in and takes a look at an incorrectly returned root with fsolve and nSolve.
