Suppose, If I have some set of non-linear equations. I want to solve those equations with fsolve, but I want solution only in real values not imaginary ones. Is there any way to restrict fsolve in this way?
Thanks in advance

That will automatically be the case, as long as the equation functions you have provided are real-valued.

If solve the equation it will give real root and imaginary root for different intial values.
No, that shouldn't happen.
There is no guarantee that fsolve will succeeed in finding a root, but the value it returns should always be real, assuming the cubic polynomial coefficients and the initial guess x0 are real.
