JacobianTargetType

class pyarts3.arts.JacobianTargetType(*args, **kwargs)

A type of target for use in Jacobian Matrix calculations.

Common for all targets is that they map data to and from the model state to the model field. That is they can transform a Vector to values in, e.g., an AtmField, SurfaceField, etc., and vice versa they can transform the fields to values in a Vector.

See model_state_vector and method involving it for more information.

Methods

readxml(self, file: str) → str

Read variable from file.

Parameters:: file (str) – A file that can be read.
Raises:: RuntimeError – For any failure to read.
Returns:: file – The file path found (may differ from input due to environment variables).
Return type:: str

savexml(self, file: str, type: str = 'ascii', clobber: bool = True) → str

Saves variable to file.

Parameters:

file (str) – The path to which the file is written. Note that several of the options might modify the name or write more files.
type (str, optional) – Type of file to save. See FileType for options. Defaults is “ascii”.
clobber (bool, optional) – Overwrite existing files or add new file with modified name? Defaults is True.

Raises:

RuntimeError – For any failure to write.

Returns:

file – The file saved. May differ from input.

Return type:

str

Static Methods

fromxml(file: str) → pyarts3.arts.JacobianTargetType

Create variable from file.

Parameters:: file (str) – A file that can be read
Raises:: RuntimeError – For any failure to read.
Returns:: artstype – The variable created from the file.
Return type:: T
