Solve a nonlinear function with one variable

2 views (last 30 days)
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

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

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.
