One sees a higher density at the curved or rapidly changing parts and a lower density where the solution curve is more straight.There are many different methods that can be used to approximate solutions to a differential equation and in fact whole classes can be taught just dealing with the various methods. We are going to look at one of the oldest and easiest to use here. This method was originally devised by Euler and is called, oddly enough, Euler’s Method.

I was trying to solve two first order differential equations like below using the Euler's method and plot two graphs with x and y as a function of t. The differential equations are: dxdt = @(x,t) -1.*y-0.1.*x;

In this case Sal used a Δx = 1, which is very, very big, and so the approximation is way off, if we had used a smaller Δx then Euler's method would have given us a closer approximation. With Δx = 0.5 we get that y (1) = 2.25. With Δx = 0.25 we get that y (1) ≅ 2.44. With Δx = 0.125 we get that y (1) ≅ 2.57. With Δx = 0.01 we get that ...

Read the documentation of your euler function. Unlike ode45 which is a variable step numerical solver, Euler's method is a fixed step solver. As such, you need to specify the number of steps you want to take, N, as the final fuction input. By having the states in columns, your derivative function will match what the MATLAB supplied ode functions such as ode45 expect, and it will be easy for you to double check your results by calling ode45 using the same f function. Also, it will be easier to take this vector formulation and extend it to the Modified Euler method and the RK4 scheme.Thanks for the tip! Unfortunately, I know about ode23 and that is not Euler's method. Sometimes ode solvers like ode23 and ode45 make hidden assumptions when calculating that you don't know about so I need to use Euler's method to clearly see the iterative loop and how the ode is being solved.
