% Computes the discrete state transition matrix for a plant. The plant equations are qDot = -skew(w)*angle + b/2 bDot = zeros(3,3); This functions uses a 5th order expansion. For |w| = 1 this routine will be equivalent to C2DZOH to 1e-14 if dT < 0.03125 sec. Since version 3. -------------------------------------------------------------------------- Form: phi = DSTM( w, dT ) -------------------------------------------------------------------------- ------ Inputs ------ w (3,1) Rate vector dT (1,1) Time step ------- Outputs ------- phi (6,6) State transition matrix --------------------------------------------------------------------------
