cannot make matlab

[simaqian]

Hello, I want to try demos in Matlab. I have successfully installed the C version on the Ubuntu 20.04. And I installed the Matlab R2023a for Linux.

[ 58%] Built target s2let
[ 66%] Built target cmocka
[ 75%] Built target test_tiling
[ 83%] Built target test_adjoint
[ 91%] Built target test_back_and_forth
[100%] Built target test_axisym_vs_directional
Install the project...

When I try make matlab, I found the problem:

(base) root@LAPTOP-SD8DEOMO:~/s2let/build# make matlab
make: *** No rule to make target 'matlab'.  Stop.

You mentioned in the website that

"It can be built using make by configuring appropriate compilers and dependencies, and then running: make matlab". I am not familiar with make. Can you describe the make matlab process more clearly? Thanks.

Please see the comments in #46 , in case that helps?

I'm afraid we're not actively developing s2let any longer. I would recomment switching to s2wav, which is a new Python/JAX code implementing scale-discretised wavelet transforms on the sphere that runs on GPUs and also supports autodiff.
