this question probably came up before, but anyway:
suppose I have a system of 3 equations and 3 unknowns,
which I want to solve numerically with NSolve.
They are polynomial of degree "n" so that I get n solutions.
Is there a way to tell Mathematica to just return the
real positive solutions, and dismiss the imaginary and negative
thank you so much for any help,
