Interface to compute exactly Jacobian matrix for some parameter when computing partial derivatives equations.

Compute the Jacobian matrix of ODE with respect to one parameter.
If the parameter does not belong to the collection returned by Parameterizable.getParametersNames(), the Jacobian will be set to 0, but no errors will be triggered.
Params:
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
paramName – name of the parameter to consider
dFdP – placeholder array where to put the Jacobian matrix of the
ODE with respect to the parameter
Throws:
MaxCountExceededException – if the number of functions evaluations is exceeded
DimensionMismatchException – if arrays dimensions do not match equations settings
UnknownParameterException – if the parameter is not supported/** Compute the Jacobian matrix of ODE with respect to one parameter.
