Description
This example is broken on Python 3:
$ python gammalib/examples/python/matrix_howto.py
...
Traceback (most recent call last):
File "matrix_howto.py", line 181, in <module>
handle_matrix()
File "matrix_howto.py", line 90, in handle_matrix
other_matrix /= 2.0 # Divide elements by 2
TypeError: unsupported operand type(s) for /=: 'GMatrix' and 'float'
The solution is to add division operators in the Swig Python wrapper for GMatrix.
I tried copying and adapting the methods from GModelSky, but it first didn’t work (same error) and then I got a segfault.
So I’m just reporting the error here.
This needs to be implemented for every class that has division operator, and Python 2 / 3 tests should be added to CI to make sure it works.
Recurrence
No recurrence.

Division operators have been added since a while, but for some reason the issue was kept open. Close now.
