Method Details

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 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

Returns:

Jacobian matrix of the ODE with respect to the parameter

Throws:

MathIllegalStateException - if the number of functions evaluations is exceeded

MathIllegalArgumentException - if arrays dimensions do not match equations settings

MathIllegalArgumentException - if the parameter is not supported
