RELEASE PySpinW v4

[mducle]

Now uses the new matlab2python script from libpymcr to generate Python wrappers for Matlab code so you don't need to use m. and so the pydoc system works.

Also fixed some small bugs:

• Remove non-ascii characters in mtimesx which was confusing mcc
• Update Python __init__.py so initialized check is global
• Fix issue in addmatrix where Python could input an integer vector value breaking the code.
• Fix bug in sw_plotspec where handles were unassigned.
• Add a new Python script to compile ctf for all Matlab found on the system (using libpymcr to find the Matlab installations).
• Add wrappers for common Matlab plotting functions (plot, subplot, [x,y]lim, [x,y]label, hold, gca, gcf etc) allowing them to be called without the m. prefix.

To test, download the files in this zip: pyspinw4_checks.zip

It has an IPython notebook spinw_test.ipynb, a CIF file needed for the notebook and a spinw wheel to install this release. Then create a new conda/mamba environment and run:

mamba create -n pyspinw python=3.11
mamba activate pyspinw
python -m pip install libpymcr
python -m pip install spinw-3.2.0.post32+0121850-py3-none-any.whl
python -m pip install matplotlib notebook
jupyter notebook

Then open the spinw_test.ipynb file and check that it runs without errors.

---

To compile this release do (from the root folder of the spinw repo)

python -m pip install libpymcr
matlab2python -a swfiles -a external --preamble "import pyspinw; m = pyspinw.Matlab()"
mv matlab_wrapped python/pyspinw/
cd python
mkdir ctf
python mcc_all.py
mkdir pyspinw/ctfs
mv ctf/SpinW*ctf pyspinw/ctfs
python -m pip install .

(to create a wheel use python -m pip wheel . --no-deps instead of the last command).
