The type of phase portrait of a homogeneous linear autonomous system -- a companion system for example -- depends on the matrix coefficients via the eigenvalues or equivalently via the trace and determinant.

    the demo of phase plane and phase trajetories are very interesting and easy to understand for the system of differential equation. Thank for your demo program.

    Why can't the top rows in the companion matrix be altered? Totally worthless.

    The Companion matrix is defined to have top row [0 1].
