$[25]$ Implement a $1-$D Golden Section Algorithm $($in C$/$C$++,$ MATLAB, etc.$)$ so that:

a$)x^{**}=$ goldensection $(x_l,x_u,e)$ where $x_l$ is the lower bound in $x,x_u$ is the upper

bound in $x,$ and $e$ is the convergence tolerance.

b$)$ Within the algorithm, call a function evaluate$(x),$ which will essentially be

$f(x).$ I need to be able to modify this function to evaluate your code.
