Compute the jacobian matrix of ODE with respect to main state.

Parameters:

t - current value of the independent time variable

y - array containing the current value of the main state vector

yDot - array containing the current value of the time derivative of the main state vector

dFdY - placeholder array where to put the jacobian matrix of the ODE w.r.t. the main state vector

Throws:

MaxCountExceededException - if the number of functions evaluations is exceeded

DimensionMismatchException - if arrays dimensions do not match equations settings
