computeParameterJacobian
double[] computeParameterJacobian(double t, double[] y, double[] yDot, String paramName) throws MathIllegalArgumentException, MathIllegalStateException 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.- Parameters:
t
- current value of the independent time variabley
- array containing the current value of the main state vectoryDot
- array containing the current value of the time derivative of the main state vectorparamName
- name of the parameter to consider- Returns:
- Jacobian matrix of the ODE with respect to the parameter
- Throws:
MathIllegalStateException
- if the number of functions evaluations is exceededMathIllegalArgumentException
- if arrays dimensions do not match equations settingsMathIllegalArgumentException
- if the parameter is not supported
