@sonystarmap Wonderful result. Exactly As I expected in theory. I wonder if the function can be expressed as f(x)=A(a)sin2πx or not. I mean if G(x,a) does not to depend on x . I try to prove or disprove it now. Maybe you can help me via Matlab codes draw G(x,a).Is it possible depends on only a ? Thanks a lot

comment To find the general formula of $\overbrace{g(g(g(…g(x))}^\text{n}=g_n(x)=\frac{A_{n}.x+B_{n}}{C_{n}.x+D_{n}}$
I understood that how to get matrix result. I had applied in my question. I will try to get result via eigenvalues . Thanks

how can that relation be proved? Please advice a method.
