Matlab question

PRELIMINARY . Create function files implementing each of the following root-finding methods following the function declarations given. This will help you consolidate your understanding of the techniques involved. Bisection method function [root, iter] = bisection(f,xl,xu, precision) False-position method: function [root, iter] = falseposition(f,xl,xu, precision) Newton-Raphson method: function [root, iter] = newraph(f,df,xi, precision) Secant method: function [root, iter) = secant(f,xi,xi_1, precision) Modified-secant method: function [root, iter] = modisecant(f,xi,pert, precision)
