Write a matlab program to implement the secant root finding method in matlab.
The function name should be Secant and it should take the equation as input whoes root has to be found and the two initial values of a and b and maximum tolerable error.
Consider the following example:
Your code should generate the following:
>> secantAssg5(@(x)(x^4+x^2+x+10),2,3,0.0001)
Xn-1 f(Xn-1) Xn f(Xn) Xn+1 f(Xn+1)
2.0000 32.0000 3.0000 103.0000 1.5493 19.7111
…..

Root is x = 0.13952
ans =
0.1395

5. In this problem we will investigate using the Secant Method to approximate a root of a function f(r). The Secant Method is an iterative approach that begins with initial guesses , and r2. Then, for n > 3, the Secant Method generates approximations of a root of f(z) as In-1-In-2 n=En-1-f (x,-1) f(Fn-1)-f(-2) any iteration, the absolute error in the approximation can be...
