Compute a MATLAB S-Function's derivatives
representing the Level-2 MATLAB S-Function block
The Simulink® engine invokes this optional method at each
time step to compute the derivatives of the S-function's continuous
states. This method should store the derivatives in the S-function's
state derivatives vector. In a Level-2 MATLAB® S-function,
use the run-time object's
Each time the
Derivatives routine is called,
it must explicitly set the values of all derivatives. The derivative
vector does not maintain the values from the last call to this routine.
The memory allocated to the derivative vector changes during execution.
