Matlab code for Euler's method

Question

0 个投票

This is my first time using matlab and I need to know matlab code for this IVP where

y' = 3y, y(1) = 2, 1=<t=<2, h = 0.5. Solve the system with Euler's method.

Look at this link:

Look at the "Formulation of the method" and "Example" sections.

Simply replacing their example with your specific derivatives, you should be able to program this up in just a few lines of code.

Here is the example copied directly from the link:

h = 1
y' = y
y(0) = 1
y(n+1) = y(n) + h * y'(n)

Are you saying you can't code that up in MATLAB with appropriate substitutions for your particular equation, range, starting point, and stepsize?

Yes. Since I am new to matlab, I don't exactly know the codes to solve an IVP. But, I do know euler's method and such.
