Can someone write an example of using the secant method to find roots of equations?

I can't use symbolic calculus. The loop needs to be limited since divergence is possible.

8y+2z=-7

3x+5y+2z=8

6x+2y+8z=26

Answer 3

[Hamid Khan]

Write an algorithm for Secant method. Implement the algorithm in matlab and approximate root of a nonlinear equation of your own choice. Find the errors in first three iterations. Display all values in list form.
