ls() pattern
Hello everyone,
I get some data in the following format and I would like to combine them to
form a dataframe.
The data is like:
cbcname1 = 0.1,
cbcname2= 0.2,
cbcname3=0.3,...
name1, name2, name2 are just some random names. I would like to achieve sth
like:
(cbcname1=0.1, cbcname2=0.2, cbcname3=0.3,......)
I am using the following codes

add points to wireframe
Hello
R-classicist won't like the following question due to there's no minimal reproducible example and the question was posted already.
Anyway I'm not able understand this rather complicated version of "add points to wireframe".
what I have is matrix 3x2000 with a dem<-(x,y,z, coordinates) (not provided).
with follwing code I want to produce the wireframe and add some

[RFC PATCHv2] Intrinsics/RTCD related fixes. Mostly x86.
Nit: in dual_inner_prod_sse, why not do both horizontal sums at the same
time? As in:
xsum1 = _mm_add_ps(_mm_movelh_ps(xsum1, xsum2),
_mm_movehl_ps(xsum2, xsum1));
xsum1 = _mm_add_ps(xsum1, _mm_shuffle_ps(xsum1, xsum1, 0xf5));
_mm_store_ss(xy1, xsum1);
_mm_store_ss(xy2, _mm_movehl_ps(xsum1, xsum1));

Patch cleaning up Opus x86 intrinsics configury
The attached patch cleans up Opus's x86 intrinsics configury.
It:
* Makes ?enable-intrinsics work with clang and other non-GCC compilers
* Enables RTCD for the floating-point-mode SSE code in Celt.
* Disables use of RTCD in cases where the compiler targets an instruction set by default.
* Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk when Opus is built in

uniform and clumped point plots
I am trying to generate two dimensional random coordinates.
For randomly distributed data I have simply used
>xy<-cbind(runif(100),runif(100))
However I also want to generate coordinates that are more uniformly
distributed, and coordinates that are more contagiously distributed than
the above.
Can anyone make any suggestions
Thanks.

Thank you. I'll follow up with the AVX code and tests for pitch code.

[RFC PATCH v1 0/4] Enable aarch64 intrinsics/Ne10
Hi All,
Since I continue to base my work on top of Jonathan's patch,
and my previous Ne10 fft/ifft/mdct_forward/backward patches,
I thought it would be better to just post all new patches
as a patch series. Please let me know if anyone disagrees
with this approach.

[RFC PATCH v1 0/5] aarch64: celt_pitch_xcorr: Fixed point series
Hi Timothy,
As I mentioned earlier [1], I now fixed compile issues
with fixed point and resubmitting the patch.
I also have new patch that does intrinsics optimizations
for celt_pitch_xcorr targetting aarch64.
You can find my latest work-in-progress branch at [2]
For reference, you can use the Ne10 pre-built libraries
at [3]
Note that I am working with Phil at ARM to get my patch at [4]

Use Windows USB drivers?
Hi,
I'm using an application that works very well with Wine but that application requires a specific USB hardware where no (and no similar) Linux driver is available for.
Therefore my question is: the application comes with a fully working Windows driver for that hardware, is it possible to use that driver to access the hardware via Wine?
Until now I could not get it work but I'd expect

Hi All,
As per Timothy's suggestion, disabling mdct_forward
for fixed point. Only effects
armv7,armv8: Extend fixed fft NE10 optimizations to mdct
Rest of patches are same as in [1]
For reference, latest wip code for opus is at [2]
Still working with NE10 team at ARM to get corner cases of
mdct_forward. Will update with another patch
when issue in NE10 gets fixed.

Hi All,
Changes from RFC v2 [1]
armv7,armv8: Extend fixed fft NE10 optimizations to mdct
- Overflow issue fixed by Phil at ARM. Ne10 wip at [2]. Should be upstream soon.
- So, re-enabled using fixed fft for mdct_forward which was disabled in RFCv2
armv7,armv8: Optimize fixed point fft using NE10 library
- Thanks to Jonathan Lennox, fixed some build fixes on iOS and some copy-paste errors

Hello Timothy / Jean-Marc / opus-dev,
This patch series is follow up on work I posted on [1].
In addition to what was posted on [1], this patch series mainly
integrates Fixed point FFT implementations in NE10 library into opus.
You can view my opus wip code at [2].
Note that while I found some issues both with the NE10 library(fixed fft)
and with Linaro toolchain (armv8 intrinsics), the work

celt_inner_prod() and dual_inner_prod() NEON intrinsics
Thank Ulrich!
Yes, using
celt_assert(1.0 + celt_inner_prod_neon_float_c_simulation(x, y, N)
== 1.0 + xy);
celt_assert(1.0 + xy1_c == 1.0 + *xy1);
celt_assert(1.0 + xy2_c == 1.0 + *xy2);
can avoid the useage of VERY_SMALL.
