jacobianInit

Workspace.jacobianInit(self: pyarts.arts._Workspace, jacobian_quantities: pyarts.arts.WorkspaceVariable | pyarts.arts.ArrayOfRetrievalQuantity | None = self.jacobian_quantities, jacobian_agenda: pyarts.arts.WorkspaceVariable | pyarts.arts.Agenda | None = self.jacobian_agenda, verbosity: pyarts.arts.WorkspaceVariable | pyarts.arts.Verbosity | None = self.verbosity) → None

Initialises the variables connected to the Jacobian matrix.

This function initialises the jacobian_quantities array so that retrieval quantities can be added to it. Accordingly, it has to be called before any calls to jacobianAddTemperature or similar methods.

The Jacobian quantities are initialised to be empty.

Parameters:

• jacobian_quantities (ArrayOfRetrievalQuantity, optional) – The retrieval quantities in the Jacobian matrix. See jacobian_quantities, defaults to self.jacobian_quantities [OUT]

• jacobian_agenda (Agenda, optional) – Pure numerical Jacobian calculations. See jacobian_agenda, defaults to self.jacobian_agenda [OUT]

• verbosity (Verbosity) – ARTS verbosity. See verbosity, defaults to self.verbosity [IN]
