Is there any preferred way to deal with hdf5 files from polars? I cannot find any mention of them in the documentation. Polars seems like a wonderful library, but this is a major issue for me.

A bit of a general question, but what is the most popular/common/easiest way of creating a custom pcore?
I have seen some examples and they were mostly done on Matlab and since I do not have Matlab anywhere, I am a bit lost here. There has got to be a proper way of doing without it!
Thank you in advance!!!
You can create it with VHDL or Verilog languages, but after that you need to make few files like .mdp and .pao, create directory move all the files there and then put the directory to a library.
Detailed information you can find in Xilinx Manual
Does anyone has code examples reading hdf5 files in F#? I cannot find any examples on SO or google. I tried hdf5.net library but could not get it to work using Python example code.
While I haven't tried it, there is some sample code available at https://rodhern.wordpress.com/2013/02/17/hdf5-f-to-octave-example/
It's the only example I know of offhand.
I am interested in using a library that supports lip reading to augment audio/voice recognition. I found out that Intel's AVCSR (which was bundled with OpenCV library) would be an interesting option to consider. Would there be any other libraries that can be used to achieve the same (lip reading to augment voice recognition)?
Also I have not been able to locate a source to download this library from. I already tried the OpenCV package from SourceForge (http://sourceforge.net/projects/opencvlibrary/) but it does not seem to have the AVCSR packages/files. Could someone who has already worked with something similar point me to the place where I can find these source files (either within OpenCV or elsewhere)?
Thank you.
In reviewing an iOS program , I found a library called libz1.2.3 or libz1.2.5.
What is the purpose of this library? Could any one explain why that library file is needed?
that's zlib - A Massively Spiffy Yet Delicately Unobtrusive Compression Library
it's used for compressing and uncompressing data (files, usually). there's a list of example applications in the wikipedia page.
it's standard for library files to start with "lib", followed by the name ("z" in this case) and then the version number (1.2.5).
[i'm kind of weirded out by the idea that no-one could answer this for 16 hours, so perhaps there's something i am completely missing here. but i don't see what else it could possibly be. it's a pretty famous, popular library.]
Okey, this is not a core programming question; it is more of a question regarding cgns (CFD general notational system) API.
I've exported a grid/mesh file from ANSYS Fluent (which was first created in Gambit 2.46), and I wrote a very simple Fortran program to open and close it (doing nothing else). To check the file is not corrupt I plotted it in Tecplot.
So, when I compiled using gfortran with the mentioned cgns and ran the program I got this error (as part of cg_error_exit_f())
ADF_Database_Open:File does not exist or is not a HDF5 file
Here is the program
program cavity
include "/usr/include/cgnslib_f.h"
call cg_open_f("Cavity.cgns",CG_MODE_READ,index_file,ier)
!check for error if so exit
if (ier .ne. CG_OK) then
call cg_error_exit_f()
end if
write(*,*)"I kind of opened the file?"
call cg_close_f(index_file,ier)
stop
end program cavity
I'm able to write both structured and unstructured grids in cgns format, without any problem.
I suspect the cgns library I'm using(version 2.5.5 packaged in Fedora 15 and Scientific linux 6.1) is built to support only HDF5, while the exported grid file is written in ADF format.
Any ideas to circumvent this or perhaps adding ADF? Which by the way is not packaged in both the distributions. Any other grid generator which is compatible with cgns version 2.5.5?
I hope I was clear. Any further info required, I would provide.
There is so much that could've gone wrong in here, and I'm afraid you didn't exactly narrow the problem down.
You said you exported a file from Fluent (what kind of a file is it? Be sure!). cg_error_exit_f() gave you an error listed. I'm assuming you have the source of the mentioned routines? In the program you include a cgnslib_f.h file - what's in it? I'm assumming the program compiled without errors of any kind, making this a file format question, not a fortran question.
Again, verify what kind of file Fluent produced.
When I ran into this situation, I discovered the following tools:
hdf2adf
adf2hdf
They are in the cgns-convert package on Ubuntu and are probably available for your distribution as well.
