matlab多变量绘图和解方程问题
各位matlab高手,我现在有下面这种类型的方程
y^2=x^3+x^2+1
请问,如何用matlab7绘图,并且求解这种方程的在实数域中的根?

问题解答：
我来补答
syms x y z, z='y^2-(x^3+x^2+1)', ezplot(z)
Codes above can give the picture, see attached file
And I don't quite understand what do you mean by 'root' here. Do you want to have function of x with variable y, or do you want to have function of y with variable x, or something else?
