EIG.calc_As#

EIG.calc_As(dense=True)[source]#

Return state matrix and store to self.As.

Returns:
kvxopt.matrix

state matrix

Notes

For systems in the mass-matrix formulation,

\[\begin{split}T \dot{x} = f(x, y) \\ 0 = g(x, y)\end{split}\]

Assume T is non-singular, the state matrix is calculated from

\[A_s = T^{-1} (f_x - f_y * g_y^{-1} * g_x)\]
