I've been searching for the way to get the output of fftw for a long time. That's a clear tutorial!

Thank you for expressing your interest. I'm hoping to resume making these videos sometime next week.

The Panda Arm (if you're referring to this: www.ori.ox.ac.uk/robots/panda-arm/ ) appears to have more DOFs than the example I presented; however, if by "the same idea" you mean an approach similar to this one, then yes, pretty much any structure can be broken down like that. But you have to bear in mind that by adding more and more degrees of freedom, you start introducing more and more redundancy that has to be taken care of somehow. Otherwise, you will end up with infinitely many solutions.

It should be possible to add checkboxes to the individual items (e.g. for multiple selection), but I'm not sure if that's what you mean.

@@damiandz6348 the treeview in Windows form has the option to make the items selectable by checkbox, yes I think your answer is also right I am not actually familiar with web development, I am starting to learn. thank you very much to the response.

That may be partly due to the fact that I usually make these videos late at night, so most of my vitality is gone by that time. However, you can probably lessen my affliction just a little bit by subscribing to my channel, if you haven't already. :)

You're welcome. Whether it's good practice or not may depend on the complexity of the particular project. If you don't have to do much event bubbling, then that's probably the way to go. If you have a lot of communication going on between different components, then the second option may be better. You may also want to resort to using some state management library, such as Blazor-State or Fluxor, if your application is really complex and many different components have to be updated automatically in response to a specific action. I have a video on the basics of Blazor-State at th-cam.com/video/rgfTiPD-O5o/w-d-xo.html (that's what I ended up using in a pretty big Blazor project I'm working on).

@@damiandz6348 I am actually using Fluxor for this project. I have only added a single feature to test it, so far. I think the first solution, for basic CRUD is fine. I may revisit at some point. Thanks again!

You're welcome! Glad to see that. I hope to make some more videos of this kind.

Thanks for the comment! If you're interested in Web development, you can also look at Blazor and ASP.NET. I've been posting videos on that, as well.

@@damiandz6348 well noted. Tbh I am just started learning this week. because I am really interested in Web Dev. thank you 😄

Hello. What was the error exactly?

@@damiandz6348 TLDR My understanding is that the std::rotate function uses a different std::iter in visual studio's msvc than g++. Answer fixed the issue by casting the fftw_complex data type to a double.

@@damiandz6348 well apparently TH-cam refuses to let me post my stack overflow link. Search "c-attemping-to-use-stdrotate-with-fftw-complex-data-yields-error-array-mu" and it should show up.

​@@OzzlyOsborne Glad you were able to fix it. Well, there may indeed be some difference between the compilers, but fftw_complex is just typedef double fftw_complex[2] under the hood. So yeah, if std::rotate fails for some reason, we can always cast it to a double pointer.

Thanks for the comment! Yeah, this video doesn't cover using CMake with wxWidgets, but it shows what probably is the most straightforward way of setting it up on Windows. What is the build system that you're trying to use?

@@damiandz6348, trying on Linux and Windows right now haha. I think I'll just stick to MSVC + VS22 + CMake - it seemed to work better, when it came to debugging the CMakeLists.txt and using C++20 Modules😅.

@@theintjengineer If you're going to use the MSVC compiler on Windows anyway, I don't really see the point in using CMake when you have a Visual Studio project that you can compile right out of the box. But maybe I'm missing something. :)

@@damiandz6348 nah, you're not😅. It's just that I also use Linux and develop there as well, so, I kinda have my CMakeLists.txt reflect that. Checking the environment and then using the corresponding kit and so on. VS has now a "feature" called CMakePresets.json that makes this all easy.

Were you following the steps on your own or were you trying to use the project I provided in the description?

For a minimum working version, you would have to change the following properties: flex-direction: row -> flex-direction: column overflow-x -> overflow-y min-width -> min-height max-width -> max-height margin-left -> margin-top And if you want the arrow to point up or down instead, also change the points of the polyline to: 0,50 50,0 100,50 Of course, you may also want to modify some names to reflect that it's no longer a sidebar, but rather a topbar, and now we're talking about its height rather than its width.

Thanks!

Hello. There are functions like fftw_init_threads(), fftw_plan_with_nthreads(int), and fftw_cleanup_threads() that you could use for explicitly controlling multithreading. The precompiled Windows binaries seem to support it. I'm not sure what you had in mind, though, and if it is really worth the overhead. It would have to be something computationally intensive (e.g., a 3-D transform) to warrant its use.

Hello! Sorry for the delayed response, but for quite some time I wasn't really active on this channel. If I can still be of some help, though, you can ask your question. Preferably here, so that maybe someone else can benefit from it.

Hello. It performs a right arithmetic shift by one, meaning the underlying bits of an integer are moved one place to the right. This is equivalent to dividing the number by 2, except that it may be faster depending on the target CPU architecture or hardware implementation. The potential performance difference (that is, more CPU instructions being generated for regular division) can be optimized away at the compilation stage, so if you were to disassemble your program, you'd be getting the same assembly code for both N / 2 and N >> 1, in which case choosing one over the other wouldn't really matter.
