md""" This notebook explores estimation of the parameters of a second-order vibration model

	$$(s^2M + K)X = BU$$

	by means of frequency-domain methods.

	The system above can be written in state-space form like

	$$\dot x = Ax + Bu$$
	$$\begin{bmatrix}
	\dot x \\ \ddot x
	\end{bmatrix} = \begin{bmatrix}
	0 & I \\
	-M^{-1}K & 0
	\end{bmatrix}
	\begin{bmatrix}
	x\\\dot x
	\end{bmatrix}+ Bu$$

	We start by constructing a sample system, the frequencies of the eigenvalues are shown below"""

This one is displayed correctly, but if I have newlines on the first and last row, it does not render
