polarch / spherical-harmonic-transform Goto Github PK

how can o use it with 3D datas?

There is no information what version of MATLAB is suitable for running the library and demo.
I've found that MATLAB demo run OK for 2015b, but fails for release 2011b, 2009b.
In version 2011b, the source of problems is expression "h.Position(3)" present in demo.
If I comment all of those expressions, demo is run OK in 2011b

There is no information what MATLAB packages are required to run the library and demo.
At least, one required package is "Symbolic Math Toolbox" (which is referenced in w3j.m module)

3. Octave works for most of the demo, but fails at the code that uses "Symbolic Math Toolbox".

The documentation of the inverseSHT function parameters is very confusing and should be updated, if possible. :)

I tried a git pull after the two recent commits. The pull, failed and I didn't pay much attention to fixing it. I removed the entire directory and restarted with a fresh clone, resulting in the following error.

You can inspect what was checked out with 'git status'

I'm unsure if this was also causing the issue when doing git pull on an existing clone. Either way, this may hinder a lot of people who are interested in your valuable repo! :)

My first impression from quickly looking up the error is that this is a minor misconfiguration of the repository, which can be fixed in the repo settings on GitHub, i.e., it requires your intervention. However, I don't have experience with LFS so far.

Hi!

I like your code very much. However, I obtained NAN while using inverseSHT when the spherical harmonic order reaches 160. What is the upper bound of the order? Can you also compute higher order transform?

Many thanks,
Jia
