Solve a nonlinear function with one variable

Hi,

I need to solve this function using Matlab in single script:

x - x^2 + 2*{sin(x)*(x-1)} = 0

Would you be able to provide a sample code and method to do this in Matlab?

Thank you very much

syms x 
eq = x - x^2 + 2*sin(x)*(x-1) == 0

eq = 

s = vpasolve(eq)

s = 

0

Thank you @KSSV for your reply.

It is quite simple to solve this exercise. Just use vpasolve(), e.g.:

syms x
Solution = vpasolve(x-x^2+2*sin(x)*(x-1)==0)

Solution = 

0

An alternative way is to try Newton-Raphson method

Thank you @Sulaymon Eshkabilov. Assueming that the solution for f1(x)-f2(x)==0 is 'x_sol' (x=0 in this case). then how would be the rest of the code look like if I want to calculate the f1(x_sol)?

Thank you again

if you are talking about NR method, see this explanation. You'd need to use [for .. end] or [while ... end] loop. See this link where a bunch of matlab codes and discussions of NR method.
