$x`(t)=Ax(t)+Bu(t)$
$y`(t)=Cx(t)$
I have three matrices. For example, the matrices are:

And using only one Matlab function I would like to get the following information:
1 Eigenvalues of the matrix A.
2 System modes.
3 ${e}^{A}$.
4 Whether or not the system is robust.
5 Resistance poles.
I am sure that all this is possible to get using only one function, but I do not know which one. Could you, please, help me find it.
Thank you.
