# From non-linear homogeneous DAE to linear state-space form

I have a non-linear homogeneous DAE $x' = F(y)$, $G(y) = 0$ where $x$, $y$ are vectors, $F$ is linear with constant coefficients, and $G$ is a polynomial with parametric coefficients.

How can I transform it into linear state-space form?

StateSpaceModel[Flatten@{x'[t]==F[y[t]], G[y[t]]==0},

where $t$ is the independent variable.
• Ah good old Flatten -- one of my favorites. :) – Michael E2 Oct 22 '15 at 23:08
