## Homework Statement

I have a Differential equation, it is in the form of a vector. It consists of 2 errors and their derivatives:

[e1 ; e1', e2 ; e2']

they are all related by:

[tex]\frac{d [e1 ; e1', e2 ; e2'] }{dt}[/tex] = [4x1 matrix] + [4x1 matrix]*e1 + [4x1 matrix]*e1' + [4x1 matrix]*e2 + [4x1 matrix]*e2' + [4x4 matrix]*[e1 ; e1', e2 ; e2']

## The Attempt at a Solution

I don't know how to input this into MATLAB for use with ODE45. All the matricies I have are constants, except for the e1, e2, and their derivatives. Can this be treated as a fourth order differential equation in Matlab even though it is 2 second order problems?

Any help appreciated.

Thanks
