Description:
 def controlcheck(controldir='default', projectdir=None, controlfile=None):
 """Define the corresponding control file within a condition file. Function |controlcheck| serves similar purposes as function |parameterstep|. It is the reason why one can interactively access the state and/or the log sequences within condition files as `land_dill.py` of the example project `LahnH`. It is called `controlcheck` due to its implicite feature to check upon the execution of the condition file if eventual specifications within both files disagree. The following test, where we write a number of soil moisture values (|hland_states.SM|) into condition file `land_dill.py` which does not agree with the number of hydrological response units (|hland_control.NmbZones|) defined in control file `land_dill.py`, verifies that this actually works within a new Python process: While trying to set the value(s) of variable `sm`, the following error \ occurred: While trying to convert the value(s) `(185.13164, 181.18755)` to \ a numpy ndarray with shape `(12,)` and type `float`, the following error \ occurred: could not broadcast input array from shape (2) into shape (12) With a little trick, we can fake to be "inside" condition file `land_dill.py`. Calling |controlcheck| then e.g. prepares the shape of sequence |hland_states.Ic| as specified by the value of parameter |hland_control.NmbZones| given in the corresponding control file: (12,) In the above example, the standard names for the project directory (the one containing the executed condition file) and the control directory (`default`) are used. The following example shows how to change them: Traceback (most recent call last):
 FileNotFoundError: While trying to load the control file \ Note that the functionalities of function |controlcheck| are disabled when there is already a `model` variable in the namespace, which is the case when a condition file is executed within the context of a complete HydPy project. """
