Maybe the following functions could be replaced by their recurrence relation
sphbesselh_derived
sphbesselj_derived
sphbessely_derived
besselh_derived
besselj_derived
bessely_derived
Also this might not be necessary:
isargsquaredinteger.m
Can you please make sure that you use always 4 spaces as tab in for loops etc. and also that you have no spaces between ,
and arguments in function calls:
f(a, b, c)
=> f(a,b,c)
.
This would be nice to maintain consistency across all functions in the Toolbox.
I added it to the TODO list
If I remember correctly, we included some (or most?) of your proposals by other pull requests. What is the current status and plan for this pull request?
I would suggest to wait for the upcoming discussions on the DAGA poster for SFS Toolbox. Then I will have a more holistic view on what is already implemented and what might be taken from this PR.
Background
Data based Sound Field Synthesis has not been covered in the Sound Field Synthesis Toolbox, so far, as most of the implemented algorithms are based on mathematical models of the desired sound field. The expansion of sound fields into circular or spherical basis functions is common approach to describe arbitrary sound fields. It is also implicitly used in Near-Field-Compensated Higher Order Ambisonics.
Scheme
The image illustrates the current implementations in
master
(blue) and the additional implementations inharmonics
(red) for the spherical case. Same holds for the circular case. The graph shows, how to get from a parameterization, i.ex_s
, to the desired sound fieldS
or the synthesized sound fieldP
.D
