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 matrix.png
So, I have to solve the (1.1) with ode45 but I have no idea of how to get started.
Any suggestions?
Thanks
