Transplant sounds interesting, I think I could use this. I don't understand though why nobody has used a more direct approach? Matlab has their python API https://www.mathworks.com/help/matlab/matlab-engine-for-python.html. This will pass Matlab arrays to/from python as some kind of opaque blob. I would guess that inside every Matlab array is a numpy array crying to be freed - in both cases an array is a block of memory together with shape and stride information. So I would hope a direct conversion could be done, at least via C API if not directly with python numpy API. But it seems nobody has done this, so maybe it's not that simple?
