Using Matlab, please explain in detail the Matlab code used and post the Matlab code. Thank you!

1. (3 points) Write a function named fibonacci numbers to compute the first n terms of the Fibonacci sequence with definition Fo=0, h=1, The input is an integer n 2 1. The output is a vector F that contains the first n Fibonacci numbers, staring from 1. Use a for loop. You can use the command F = zeros(1,n); to create a row vector F with n zero entries, and update each entry based on the definition. You may need to consider some special cases when n = 1 and n-2. Test your function with input n1,2, and n 10 and document your result. (4 points) Find a root of the equation xexp(-2)cos(x) 0 using .Bisection method on [1,0; . Newtons method with x0; .Secant method withx0 and the x11. Stop the iteration process at step n when x-x-1lS le - 7. Compare the number of iterations required by each method 3. (3 points) Find the root of the equation sin(x) 0, using Newtons method starting with xo-1. Do you observe fast or slow conver- gence? Explain why
