Numerical Solution of Initial-Value Problems

The MATLAB routines ode23 and ode45 can be used to solve the system. A MATLAB function must be created to evaluate the slopes as a column vector. The function name in this example is exode(x, y) which must be saved first in the hard drive with the same name exode.m.-----% Example 4.3-2 function to evaluate the slopes. function y12 = exode(x,y) ................
