• Just me, or is the 50g low in solving differential equations?

  Hi all

  I used Ti-89 s widely in the past, as well as the Ti-NSpire CX CASE and now the 50 g for about 1.5 years. I love some aspects of the 50g (sensation of keys, ease of unit, RPN conversion), but I can't help but notice some areas where it reallllly hangs out of the competition.

  It is an example that I really noticed recently in solving differential equations. So far, several examples I've tried (all immediately resolved by my Ti - 89 and Nspire CX CASE), the 50g smothered on each.

  A very simple example: solve y "= - 9.8, with boundary conditions y (0) = 2.9 and y'(0) = 3.8.  This can be solved by hand in about one minute, but the 50g can't do. If I input ['d1d1Y (X) =-9.8' ' Y (0) = 2.9 ' ' d1Y (0) = 3.8 '] in level 2 on the stack, then 'Y' on a level and then run desolve, it returns "Error: Undefined result.

  I missing something here, or is - this really unable to resolve such a differential equation based? I thought that advanced and 'better' mathematical capacity HP CASE was meant to be one of the reasons why it takes precedence over offers from Ti, but I must say, so far I do not see that.

  Hello!

  Try with the exact numbers:

  ["d1d1Y (X) =-49/5 ' ' Y (0) = 29/10 ' ' d1Y (0) = 19/5 '"]

  « Y »

  DESOLVE

  (after SIMPLIFICATION) You'll get years:

  {Y (X) =-(49*X^2-38*X-29)/10}

• Cannot read simple games on Satellite L30-14

  Hello

  I can't play even simple games on my laptop, such as Stronghold Crusader (what sys requirements are ok for my setup).

  The game always freezes at the main screen of windows after the launch. How can I solve this problem? The game's website says nothing about this problem.

  Other simple arcade games also crushing in the main window after the launch!

  Hi Kamal

  Did you use the original or a copy?
  I also play this game. It s nice. My phone supports a P4 with 512 MB ram 1.8Ghz. The graphics card is a radeon 7500 mobile. It s a little bit older.
  However, I don t think you laptop has a malfunction or there is something wrong with the hardware.
  I see that your device supports only 256 MB memory. Well, I m not 100% sure, but it sounds like it could be a reason for the game from problems.

  What about ram increases? upgrade memory could be the magic key

• How to solve an equation that has integration

  Dear Sir.

  I need to implement an equation like below:

  

  I have checked several VI mathematics and box tools treatment but unable to fulfil my obligation of signals. Kindly help me with suggestions.

  with respect,

  Sri

  This isn't really a question of LabVIEW, but a simple calculation a.

  The integral show you is a definite integral between values: 0 and 'b '. I guess that the 'a' is a constant value, so just integrate it by the variable 'b', simply by using the rule of the definite integral:

  -2 * a * (b - 0) = - 2ab.

  So if you have the value of a and b, you can use just to function multiply in LabVIEW.

• Solve complex equations stored on the HP50g

  Hello

  I stored the 2 equations Δ & K, but when I try to solve in the Num. solv. I get the message bad guess (es). I searched on google and it seems that it is because I work with complex numbers and the num solv. can't handle them.  However, I have not found the way to solve them. I use two equations, so it would be great if you could help me find a solution where I can solve them enter the values of the variables, just like with the num solv.
  

  

  FYI, make sure you go back and read your old post... the method to enter the equations with existing values using EQW is demonstrated in the last entry and unfortunately was added after you received the answer to your question...

  Here's the simplest method

• non-linear system Solver more equations than unknowns

  Is it possible to solve a nonlinear system with more equations than unknowns in LabView. I do a triangulation and data from several sensors, so I'm able to write 6 equations in order to get the 3 coordinates (x, y, z) as a solution. In LabView, I was able only to solve a system of 3 equations with this 3 unknowns, but I would use the set of 6 equations in order to obtain a more accurate solution, given that some measures can be noisy.

  Thanks in advance

  You can use the non-linear curve code to solve this problem. Consider the following system:

  3XY + y - z = 12

  yx + x ^ 2 + z = 12

  x - y - z = - 2

  Arrange to get 0 right side. x, y and z are the paramneters to be in shape. The entrance to the curved Fti.vi Y non linear will be an array of three zeros. Initial settings will be an array of three values, for example [1 1 1]. An example is attached.

• Solve linear equations - Block tridiagonal matrix

  Hello

  I developed a vi that can be used to solve tridiagonal systems by block of equations by Thomas algorithm. These systems are usually in the finite differences method used to solve equations in partial derivatives.

  For iterations of 1000 times, its time is ~ 500ms. Now, I want to finish the work within 100ms. is possible to improve the performance?

  Thanks, Jong Hyun

  For details of the Thomas algorithm, please see wikipedia Web page, http://en.wikipedia.org/wiki/Thomas_algorithm. Note that it describes how to solve tridiagonal linear equations, but same logic can be applied to block tridiagonal equations.

  * If you use the vi sparse SLE of analysis multi-hearts and Sparse Matrix Toolkit, the elapsed time is 450 ms ~

  LabVIEW basic/full/pro all use Intel MKL library for linear algebra on MS Windows and Linux.  Intel MKL designed to be very fast for large matrices and breaking a problem given out to take advantage of the different levels of cache. Linear algebra calls go through several levels of functions, including size controls, if any, and may allocate memory for the workspace each call, before finally calculate the result.  This overload problem is evident when the matrix is so small (3 x 3).

  I coded matrix-matrix, versions multiply, matrix-vector multiply, and matrix opposite in the case of 3 x 3 explicitly in soil using the structure in place and full indexation (no loops, all scalar operations).  This eliminates the overhead of controls and allows better and placeness.  This brings your reference point down for ~ 70ms on my machine.  Unfortunately this requires significant code changes if you change the block size, but it provides good performance.

  "I think that, if I can save each submatrix conversely in the first round and use several times, then speed will be better."

  I agree.  You should be able to calculate the most sweeping toward the front of the algorithm and simply replace the submatrices changed and still solve before.  This may mean re - organize the variables to have the submatrices updated or modified down to the right of the input matrix.

• What I can do (and what cannot) with simple editing DPS?

  I want to publish a catalogue of customer in the iPad and also for the web and print. Using inDesign and DPS appears as the fastest and effective way for it, so the questions...

  • I want interactive content on this (video, hotspots, natural interactions, etc.) and perhaps (in a few months), updated the content on the fly. The work of editing simple for this panorama?
  • Using simple DPS and the SDK allows me to increase the level of customization in the application?
  • For deployment... using a Mac is a must, or I can do it through Windows? (something like the publication of an AIR application for iOS via Windows?)

  I appreciate your answers.

  Kind regards!

  PS. Sorry for my English!

  1. all our interactive works in simple editing. If you are a customer of creative cloud you can build updates as much of the application you want as long as you stay client CC.

  2. There is no "SDK". You can customize limited aspects of the app (mainly icons and splash screen), as well some interactivity integrate you your content.

  3. you can develop your content in InDesign on Windows, but to build the final application and to submit it to Apple, you must be on a Mac.

• Delete the e-mails on the main account and cannot access Icloud

  Hello

  I deleted my email main and put Icloud account on my Iphone but not my Mac of Air. Now I can't access Icloud on my Mac or sync my devices. As a dimwit, I forgot my old email password, which today does not exist in any case how can I rectify this?

  Thank you

  So, you actually changed the Apple ID of the email from the old address to the new? If Yes, then you can connect to your Mac using the current password.

  If you have created a brand new Apple ID for your new email address, you will need to sign in the old email address (it does not matter whether the actual email account exists or not, ID Apple still doesn't work), then click on reset password: Apple - my Apple ID. If you have forgotten the answers to Security Questions, you will need to contact Apple support: ACCOUNT SECURITY SUPPORT

  I hope you just change the ID... it's much easier!

  See you soon,.

• exe cannot find simple vi

  I have problems with exe created finding even the simplest of vi when I try to run them. I created a new project today LV2009SP1 with 4 Subvi in the library of 34401 and built instruments in a .exe. I tried to run the exe on my development machine and he asked me to find these Subvi. The simple block diagram of high level vi is attached.

  I tried mass compile the library of instruments

  I can't fix LabVIEW because it's SP1 so I do not have the disks.

  It's just and example of the problem.

  The vi works fine in the development environment.

  The range of the instrument looks very good.

  The project is very good, that is, that it opens not dirty.

  In the menu options, I left the default search paths.

  Any ideas I could try?

  
  

• Palm Pre constantly goes Offline webOS 1.3.5.1 called Sprint, cannot solve

  I use this phone since September 2009 and have not had this problem before. Last week when I updated for webOS 1.3.5.1, my phone constantly goes offline (top right corner it says "Phone off line"). It's very annoying because my calls back goes straight to voicemail and I can't text or surf the web when disconnected. I'm losing business from clients.

  At first, I thought maybe Sprint a signal outtage questions (due to cold front?), so I waited a few days and I'm still having the same problem.

  I called Sprint and they have tried to reset my connection and then asked me to stop and remove the battery for 3 seconds. I did it and I'm still going through the same problem. I called Sprint again and they told me to take my phone to the nearest Sprint Store to get a diagnosis. It is such a waste of time. Everybody runs into this same problem?

  If anything, I'll just buy another phone (never a Palm again)

  I've only had problems with this phone:

  -Memory leaks/major lag

  -When I try to close an application by dragging it to the top, he comes back down

  -When I only have 2 cards and try to open another, he said that too many cards open. I close all the cards and open just this one alone, and he says the same thing. I have to restart the phone, because everything works super slow

  -Memos 'mysteriously' disappear and then re-appear again

  webOS updates - screwing my (mafia game) Apps

  Unfortunately, you just need to start disabling the services until understand you that one hangs luna.  I began by killing the accounts of instant messaging, calendar, contacts and finally struck by e-mail when he stopped with the stupid phone offline behavior.  Pretty well, I knew it was e-mail, but wanted to exclude anything else causing her grief.  Pretty sad, the device cannot handle 500 emails in the affirmative, but I think that I have even more than that in my Inbox and it works.

  Such joy, pay for the device, markets service and crappy sprint as end users have to work around their bugs, redo our emails and others to adapt to their ideals of how things work on the interwebs just to make it work.  More disconcerting, it's Palm never bothered to acknowledge or respond to one of my posts on the debacle, sprint is clueless to do something with 4 back with probably 10 hours of support calls (typical cellco), and obviously it's not just me as the wheel that squeaks here...

  This behavior began in 1.0 and apparently is present through 1.3.5.x with many complaints on the way, so wtf is palm doing to fix this?
