- All Implemented Interfaces:
MultivariateMatrixFunction
public class JacobianFunction extends Object implements MultivariateMatrixFunction
Class representing the Jacobian of a multivariate vector function.The rows iterate on the model functions while the columns iterate on the parameters; thus, the numbers of rows is equal to the dimension of the underlying function vector value and the number of columns is equal to the number of free parameters of the underlying function.
