Attempting to set the matrix directly fails

[Christopher Volpe]

With "ms" as a MeshSet, I call the following code:

ned2enu = np.array([[0,1,0,0], [1,0,0,0], [0,0,-1,0], [0,0,0,1]])
ms.set_matrix(ned2enu)

When I do that, the traceback ends with this:

File "D:\Volpe\TestProject\main.py", line 46, in parse_glb
ms.set_matrix(ned2enu)
TypeError: foo() takes 1 positional argument but 2 were given

Note that "foo()" is not something that I have defined.

Any idea what's going on here?

You need to give the name of the parameter in the call of set_matrix:

Oh, thanks. I'm a bit of a Python newbie here. I thought the parameters could be supplied positionally if I specified them in order and accepted the default for anything not specified. I didn't realize specifying them as keyword args was mandatory.
