% Itfinds the velocity using RK 4 method
clc; % Clears the screen
clear all;
F = @(t,v) 9.81 - ((0.28/85) * (v^2));
t0 = input('Insert the value of the initial time: ');
v0 = input('Insert the value of the initial velocity: ');
tfinal = 20;
h = input('Insert the value of the step size: ');
v = RK_4(F,t0,h,tfinal,v0);

You need to write the RK_4 function. Right now, RK_4 is the name of your current script. You can find one implementation of the Runge Kutta-4 algorithm here: https://www.mathworks.com/matlabcentral/fileexchange/29851-runge-kutta-4th-order-ode
