Reverse and pseudo inverse Matrix on FPGA

• Matrix inversion complex on FPGA

  Hello

  I implement a simple code on SMU-7966R. I need a function that calculates the inversion of a complex matrix (fixed-point). I was wondering if there is an existing library that provides the service or I must apply myself.

  Please can someone enlighten me?

  Thank you.

  I don't quite know librares for the execution of complex matrix inversion.

  There are two ways I used for the development of own implenetations. Both methods involve the decomposition of the matrix A through rotation matricies.

  (1) the QR decomposition through Givens rotations where is QR. This method breaks down the matrix in a unitary matrix Q and a upper triangular matrix R. The inverse of Q is simply its transposed to Hermetian because it is unitary. The inverse of R can be solved for by back substitution. Multiplying the inverse of Q and R gives the inverse of a.

  (2) use the signular A value decompositon to get two unit matricies u and V and a diagonal matrix S of the signular components. Again, reversing the unitary matricies is simply the transposed to Hermetian. The inverse of the diagonal nmatrix is only taking the reciprocal of the diagonal elements. The SWINE vesicular disease can be performed using an algorithm called the cyclic Jacobi method. This method is slightly more complicated than the QR decomposition since it requires an additional rotation matrix, but it avoids the back problems through substition.

  These two processes are iterative and converge to the exact solution as the number if iterations increases. While math can seem a little daunting at first, there is a lot of literature on these topics including different FPGA implementations. Just google 'FPGA QR Décomposition' or 'Method of FPGA Jacobi'.

• Select reverse and remove the effect from Photoshop to Illustrator

  Hello

  I'm new to Illustrator and do my best to understand how it works! I'm used to working with Photoshop and there are some things that I could do it on Photoshop and am now trying to find a way to make it look as I want... So here goes

  I'm looking to have this effect on Illustrator. (For those who you don't see the image, mimage is a globe with the text that appears only on continents. The text disappears when the image is empty. I forgot to save it as a png, but white is transparent.

  

  I managed to write my text in Illustrator and change the text to "Color Burn" effect, so that it looks the same on all continents. However, I am unable to remove the text where it leaves the other layers. The text remains black where the background is transparent.

  

  So I was wondering if there is a way to remove the text outside the continent. The same effect, you should achieve in Photoshop by selecting reverse and removing the text (pixelated).

  Make a copy of the shape of the continent. Select the copies, and then choose the command object > path > make a compound path.

  Then use the new compound path as a clipping on the text mask. With her before she and the text and the text selected, choose object > path > make a clipping mask.

• Difference between Pseudo-classes and pseudo-element

  Hello

  Does anyone know the real difference between Pseudo-classes and pseudo-element?

  The two are very different, but I can't yet tell them apart.

  And I read on some website that there is selection controls, selector of Pseudo-classes and pseudo-element. For good to mix people, understand me!

  
  

  The pseudo-element only I use are a: link, a: visited, a: hover. And I were Pseudo-classes appeal!

  
  

  Can someone can clarify for me please?

  
  

  Thank you!

  Pseudo-elements are so-called because they are not real HTML elements - for example there is no HTML didn't call first line tag, but using CSS you can apply a style to the first line of a paragraph, for example using: first-line. A pseudo-class is called a class because it does not select a property of an HTML tag (e.g. a: hover, targets of the HTML tag), but because the hover is not a class attribute, the designer has added to the markup, it is called 'Nick'). Using double colon for Pseudo-elements is the new syntax (standard CSS3) and is not always understood by all browsers yet, sometimes, you need to use a single colon.  The double colon comes to more easily differentiate Pseudo-elements (:) and Pseudo-classes (:).)

• How to use the modules of the series and two different bitrates in FPGA mode on cRIO 9075

  Hello

  I have a project with modules namely NI 9227 (module 1) and NI 9234 (2 Modules)

  The project is running and I use the file writing PDM and found that two channels is in the TDMS file while I download the file using FTP the cRIO.

  1 - my quesition is the addition of a second rate in the FPGA?

  2 - Why is it TDMS connect 6 channels and 4 channels?

  Thank you

  Attached to the project with two screws

  Hello Ihab,

  Sorry for the late response here; just saw this message! If you want to keep synchronized modules then definitely stick with the master configuration and slave for your two modules. Note also that you can taste a little faster with the NI 9234 as your master module (since its time base main internal is 13,1072 MHz instead of the time base of the 9227 12.8 MHz).

  Also, see the tips and information in our troubleshooting guide for the synchronization of the series C with LabVIEW FPGA modules:

  I hope this helps!

• project and the strange behavior of FPGA v

  I had a strange problem with my main project and the FPGA inside screws.

  It seems than a recent revision/replacement of a part of the code (replaced subVIs with the latest revisions with different names) prompted the VI to load screws unused when I save it.

  The story gets more strange because I can create a totally blank FPGA VI within the project and it still load the same SubVIs when I save it.

  I can save repeatly the VI and the same (now nonexistent) subVIs will be charged each time before the economy can complete

  The SubVIs are not displayed in the VI hierarchy and are no longer in the project at all - but are always loaded by a VI that does no resemblance or relationship to the original VI.

  Is my project completely broken?

  If Yes is there a way to fix without starting from scratch ?

  Thanks for any help in advance

  Dan

  you have a screw under the fpga target who could still make reference to the missing subvis? If the project think that you still have a dependency on these missing subvis, they will appear (with a warning that I think) to under the item "dependencies" of the target fpga. When you save a vi in the context of fpga, labview support the other screws in the same target to ensure they are still valid and up to date of the accounting information. If you have any other screws which are still divided on disc (even if they set up on top of the load), you will have to wait until they take whenever you save the vi in question.

• saving and recalling Panel configuration on FPGA

  First of all, I'm a first time Labview user.  The application is an FPGA on a surfboard OR-9146.

  My question is, I want to save the settings of front panel, when I exit the application, and then remember them the next time the application is started.

  Seems to be a few ways to do this, but are not supported with the FPGA module.

  The application is pretty simple timing and the host PC Windows will provide a graphical interface for the operator.

  Someone can correct me if I'm wrong, but this task is more tedious, then it must be.

  The normal way to do it on the FPGA is to plop in a FPGA read function for each control on the Panel before the FPGA, then write to a file.  Probably using a function OpenG, but really something like binary writing might work if you do not expect to add/remove items.  Then when the application starts, you should return to the ploping of the process down a FPGA write the function for each control.

  There is now an easier way of slightly in theory works in a limited use case.  The FPGA VI executing is just like a normal VI and you can get a reference to it.  Here, you can run the Panel writing OpenG INI, INI reading Committee.  Here are two functions canned that save tons of time.  The reason why this wouldn't work for most developers FPGA is now because in the end, the goal is not to see the FPGA VI and only runs the file bit and call in the FPGA using the hooks that neither offer.  Looks like you'll have the VI watch in any case if this method can really work for you.

  She sucks a bit and I think it would be nice if NEITHER had a way to read and write all the controls in the Panel before FPGA for such things.

• I select "reverse" and the printer still prints on page 1; How to print the last etc., first page

  I select 'inverse', so the printer starts to print on the last page and ends the first and it still prints page 1, leaving me to CPlacez pages in the order manually.  How to do this.  My last HP had no problem;  I have a 6100

  Please try this:

  1. Enter the control panel > devices and printers.
  2. Right-click the printer icon, click Printing Preferences.
  3. Select the Advanced tab.
  4. Set the order of the Pages as back and forth.

  Additioanlly, check the same setting applies to the program you use as custom preferences can be kept for a specific program:

  Open the file that you want to print, the click file > print.

  Click Preferences, and then check the order of the pages defined as Front-to-Back.

• Play reverse and continue on a point

  Hi guys,.

  I and item and I want to do when I click on that element, it starts to play reverse chronology for 1 second and after that, he continues to play the timeline to another point. How can I do this?

  Hi, Mandi-

  You must set a trigger to your jump point and then look into testing for the sym.isPlayDirectionReverse () API.  So, something like:

  will be true or false

  var playReverse = sym.isPlayDirectionReverse ();

  If {(playReverse)

  SYM. Play ("Newlocation'the");

  }

  Hope that helps!

• Reverse and backwards overview

  I ran into an intermittent problem any files from AVCHD Panasonic (MTS extension) PP CS6. Sometimes, when I saw a file imported, it appears reversed (negative image) and upside down in the control screen. The clips I saw after appearing in the same way. I can solve the problem out and raising PP. BTW, I copy all the content on the map on which I record, with no changes to the structure of files on my hard drive.

  All the world run into this kind of problem? Any help troubleshooting and fixing very appreciated.

  Don't think it was a graphic driver problem - the problem only occurs when you are working with types other than AVCHD files. I did some troubleshooting and discovered that the problem seems to be related to the scrub of hovering in the media browser. I disabled this feature (in the Panel menu) and the problem has not occurred since. Hope this helps someone else down the line.

• selective reverse and reverse?

  Hello world
  
  in the defination for the model tab, we have the option 'display metadata changes in the model tree '.
  
  I used to think whenever I make changes in my columns related to the source or target, I'll get the changes to update here, but I tried to change the length of the columns. It forces to see the place, so I did selective opposite to this table and he showed me.
  
  but when I do the opposite right click I see all the changes and all temporary tables created by ODI.
  
  1. What is the diff between opposite selective and do a right-click reverse?
  2. how the changes automatically appear in ODI whenever I have changes to the structure of the source or target. without clicking on the back?
  
  Thank you

• Our processor was reversed and now even if we have internet, other operations on the computer are unusable or very limited.

  Last night, our processor has been spilled and although he fell very hard, we have no audio data, we are unable to change the screen resolution, and we are unable to turn on our safety Center, among other things that bothers. We have access to the internet. I have checked the cables and connections but can't find nothing obvious. We need to operate the computer in safe mode. Any help would be most appreciated. Elen

  Hi Elen,

  1. what happens when you start in normal mode?

  Safe mode starts Windows with a limited set of files and drivers. Startup programs do not work in safe mode, and only the basic drivers needed to start Windows are installed.

  Start your computer in safe mode

  This can also occur if the cables and cards are not connected correctly. You can check if the cables and cards are connected correctly.

  Hope this information is useful.
