How do I compute the absolute error n = |xn − xr| for n = 0, 1, . . . , 50, where we take the output xr from MATLAB’s fzero function with initial guess xinit = 1 to be the “true” root, given this.
xn = bisectionMethod(f, a, b, numiter)f1= @(x) cos(x)-x;f2= @(x) exp(-x^2)-x; f3= @(x) (x^3)-(1/2);x1= bisectionMethod(f1, 0, 1, 50);x2= bisectionMethod(f2, 0, 1, 50);x3= bisectionMethod(f3, 0, 1, 50);
