Hi everyone,

I am an aerospace engineering student who is approaching to the numerical analysis exam.

I have to solve the second-order wave equation with ode45 tool.

So, I have this prolem

I approached this way

and so

with the following IC and BC

(ICs)

(BCs) that become

So I have something like this

(1.1)

where

is a vector and A is a block matrix just like this one

So, I have to solve the (1.1) with ode45 but I have no idea of how to get started.

Any suggestions?

Thanks
