• Resolution of a system of nonlinear equations

  Hey guys,.
  Currently, I am trying to solve a set of nonlinear equations in LabView with the help of MathScript and MATLAB code. I am trying to create a code of work for hours, but I have not yet reached this goal.

  System of equations:

  x ^ 2 + y ^ 2 + z ^ 2 - R1 ^ 2 == 0
  x ^ 2 + (y - Y0) ^ 2 + z ^ 2 - R2 ^ 2 == 0
  (x X_0) ^ 2 + y ^ 2 + z ^ 2 - R3 ^ 2 == 0

  R1, R2, R3, X 0, Y0 are known.

  A possible solution in MATLAB (assuming that X 0 = Y0 = 100, R1 ^ 2 = R3 ^ 2 = 11000, R2 ^ 2 = 9000):

  Create myfun.m with the contents:
  function F = myfun (x);
  F = [x (1) ^ 2 + (2) x ^ 2 + x (3) ^ 2-11000;]
  x (1) ^ 2 + (x 2-100) ^ 2 + (3) x ^ 2-9000;
  (x 1-100) ^ 2 + x (2) ^ 2 + (3) x ^ 2-11000];
  end

  The initial value for iteration:
  x 0 = [50 50 50]

  FIX:
  fsolve (@myfun, x 0)

  => Works great!

  Now, I tried all these stuff plug a MathScript node:

  function F = myfun (x);
  F = [x (1) ^ 2 + (2) x ^ 2 + x (3) ^ 2-11000;]
  x (1) ^ 2 + (x 2-100) ^ 2 + (3) x ^ 2-9000;
  (x 1-100) ^ 2 + x (2) ^ 2 + (3) x ^ 2-11000];

  x 0 = [50 50 50];

  Ground = fsolve (@myfun, x 0);

  This is where the problem begins.

  When I try to run the program, I get the following error message:

  A function is defined in the present text. You must save and call
  function with input values appropriate to run the function.

  I can't really understand, what I did wrong and I would be very grateful if someone could help me.

  Kind regards

  Hello

  MathScript does not support inline function defined by the user (UDF). What you need to do is

  1. Define the UDF in a ".m" file. Give this file the same name as your UDF ".m".
  
  
  2. Save the file ".m" MathScript search path. By default, the search path is the LabVIEW data folder.
  
  
  3. Pass the name of the file ".m" as the first string input to the fsolve function in the MathScript node.

  I enclose my .m file and snapshot of the MathScript node. The result I got is [50, 60, 70] which must be correct.

  

• monitor calibration system

  Can anyone recommend a good monitor calibration system (budget $300 limit)? I'll work on a book intended for offset printing press 4 colours, and the color is a major factor in the book. I'll never be, so I think it's time to take seriously the monitor calibration. I'm working on a new iMac, so I think that a good calibration system would be useful.

  Any thoughts? (Dumb question)

  Thanks in advance.

  My problem started when my laptop does not start and instead would show only a black screen, offering the ability to ctrl + alt + delete to start. I tried this and still no success. Finally, it took me to a screen asking password "Administrator"? Of course, I've lost my and forgotten.

  I would really appreciate a solution to this problem as soon as possible because my family is about to turn into chaos. Help!

• Algebraic manipulations of solutions to differential equations

  Hi, guys

  I found the general solution of the differential equation y "-3 t = 1 using the command DESOLVE. I did it manually first and the answer I got was: 1/2 t ^ 3 + 1/2 t ^ 2 + C1t + C2; However, when I do with the calculator that I get is: (2cC0 + t * cC1 2 + t ^ 3 + t ^ 2) / 2.  I tried everything in the ALG menu to get rid of the 2 in the denominator. Nothing has worked.  I'm in Exact, symbolic mode.  Am I missing something?

  Thank you very much!

• Solution of the equation to convert HMS on HP33S.

  When I program the equation: d = (l /(2*pi*r)) * 360 which is the delta of a curve, my answer is returned in decimal degrees.

  How can I enter this equation to get my answer to return to HMS?

  Thank you everyone!

  Hello

  You can enter the equation as:

  D =-> HMS ((L /(2*pi*R)) * 360)

• non-linear system

  I use nD system no single linear solution.vi trying to solve two equations in two unknowns. I know how to do this.

  But the question is how can I add a variable (that I don't want to evaluate non-linear system ND unique solution.vi) for example 'c' I want at the entrance of another VI. Similar to the way used in a formula node.vi, where you can add an entry.

  One way to do this is to use the substitute Variables.vi.  I have modified your VI to take the name of the parameter as an input ('c') and converted the numeric value to a string to create a substitution rule.

  Hi Dotag,
  

  1. you are using an HP computer?
  2. in the error message is display Microsoft Solution center or HP solutions Center?

  3. If the HP Solution Center, which seems to be a common pop-up message on HP computers.

• Pop-up message & system crashes when I try to open a folder

  I also have the same problem! whenever I try to open a particular file, this message appears. If I try to report the problem or ignore it, the system gets hanged... I use windows xp with sp3. can help you guys! all the movies I downloaded the folder I mentioned! :(

  This could be the result of a corrupted file system.
  The solution is to run a check disk (chkdsk) on your hard drive.  Follow the instructions in the following article. Select it "/ F" or "/ R" if run from the command line option, or check the two options if running from the GUI.  He will complain that it cannot check until the next reboot.  Answer 'Yes' or click on 'OK' and restart your machine.
  WARNING: This check can last for hours and can not be interrupted, then pick a time where you don't have your computer for a period of time to execute.

  Why do you think that the restoration of the system is the solution to your problem? It may be, but there are many problems that can cause a computer not to start where using the system restore won't help.
