double[] computeParameterJacobian(double t, double[] y, double[] yDot, String paramName) throws MathIllegalArgumentException, MathIllegalStateException
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.
