I'm trying to call the gf function of the Communication Toolbox for which I have an active license:
>> license('inuse')
communication_toolbox
matlab
signal_toolbox
simulink
but I get the following error:
License checkout failed.
License Manager Error -4
Maximum number of users for Signal_Blocks
reached.
Try again later.
Troubleshoot this issue by visiting:

Diagnostic Information:
Feature: Signal_Blocks
It seems that Signal_Blocks is part of the DSP System Toolbox (even if I can't find it). Is it normal for a class of a toolbox to require another toolbox?

Yes, in MATLAB, it is common for one toolbox to require functions or features from another toolbox. MATLAB toolboxes are collections of specialized functions designed to perform specific types of tasks. Some toolboxes are built to complement core MATLAB capabilities and may depend on the algorithms or functions provided by other toolboxes to perform their intended operations.
