MATLAB: How can i solve nonliner equation

equationfsolvehow can i solve nonliner equation?MATLABnonlinearraphson

I tryed to find roots of nonliner equation by use all posible codes: fsolve, fzero, fixed pointes, raphson method.

Equation is: x^2-x+1.

Help me.

look at documentation on the "roots" function, (ie type help roots).

hi, what is the problem exactly !

delete the part :

   real(r1);real(r2);
    y1=imag(r1);y2=imag(r2);

I think the code is fine :

 Enter a: 2
 Enter b: 2
 Enter c: 2
 This equation has two imaginary roots
 r1 =
-0.5000 + 0.8660i
 r2 =
-0.5000 - 0.8660i
