Could you create me a secant code in Matlab program? That's I can keep it and use it for any time?

Expert Solution

In this program for secant method in Matlab, first the equation to be solved is defined and assigned with a variable ‘a’ using inline( ) library function. Then, the approximate guess values and desired tolerance of error are entered to the program, following the MATLAB syntax.

% Secant Method in MATLAB

a=input('Enter function:','s');

f=inline(a)

x(1)=input('Enter first point of guess interval: ');

x(2)=input('Enter second point of guess interval: ');

n=input('Enter allowed Error in calculation: ');

iteration=0;

for i=3:1000

x(i) = x(i-1) - (f(x(i-1)))*((x(i-1) - x(i-2))/(f(x(i-1)) - f(x(i-2))));

iteration=iteration+1;

if abs((x(i)-x(i-1))/x(i))*100<n

root=x(i)

iteration=iteration

break

end

please rate it up thanks :)

I need someone to create a program for me: Create a program that takes as input an employee's salary and a rating of the employee's performance and computes the raise for the employee. The performance rating here is being entered as a String — the three possible ratings are "Outstanding", "Acceptable", and " Needs Improvement ". An employee who is rated outstanding will receive a 10.2 % raise, one rated acceptable will receive a 7 % raise, and one rated...

In MATLAB write a function secant.m to apply the secant method. function [x,i] = secant(f, x0, x1, tol, maxiters) [x,i] = secant(f, x0, x1, tol, maxiters) performs the secant method with f(x), starting at x_0 = x0 and x_1 = x1, and continuing until either |x_i+1 - x_i| <= tol, or maxiters iterations have been taken. The number of iterations, i, is also returned. An error is raised if the first input is not a function handle. A warning is...

This is a Matlab Question Create MATLAB PROGRAM that can solve First Order Linear Differential Equation ( 1 example contains condition and the other does not have condition). 1. ty′ + 2y = t^2 − t + 1, y(1)=12 The correct answer is y(t) = 1/4 t^2 − 1/3 t + 1/2 + 1/12t^2 2. (x-1) dy/dx + 2y = (x+1)^2 The correct answer is y = (x(x+1) / x-1 ) + C(x+1) / x-1 The correct answer is
