Hi all
I'm solving a set of second order equations that can have more than one root(answer) that can satisfy a certain condition. The problem is that most of the time it stops at the first solution it finds that's true that it could satisfy the one condition I define externaly out of fsolve. For example if My answer is a set of coordinates of a point, I don't want that point have more than a certain distance from a certain point otherwise fsolve should continue. How do I do this?

It is not possible to use constraints with fsolve()
What you can do is fmincon() on the square of your function; when you are looking for a zero, then provided the function is real valued, the square of the function will have a minimum at the zero. fmincon() can have linear and nonlinear constraints.
