TABLE OF CONTENTS Let's examine the code for ode23tx. Here is the preamble.
function [tout,yout] = ode23tx(F,tspan,y0,arg4,varargin) %ODE23TX Solve non-stiff differential equations. % Textbook version of ODE23. % % ODE23TX(F,TSPAN,Y0) with TSPAN = [T0 TFINAL] % integrates the system of differential equations % dy/dt = f(t,y) from t = T0 to t = TFINAL. % The initial condition is y(T0) = Y0. % % The first argument, F, is a function handle, an % inline object in MATLAB6, or an anonymous function % in MATLAB7, that defines f(t,y). This function % must have two input arguments, t and y, and must % return a column vector of the derivatives, dy/dt. % % With two output arguments, [T,Y] = ODE23TX(...) % returns a column vector T and an array Y where Y(:,k) % is the solution at T(k). % ...
