calculation using the formula node needs two clicks

• Initialization of an array to match another size of array using the formula node.

  I want to get a few different pictures of the same length and constants in the formula node and output a table corresponding to their length after some minor calculations. Another post, I discovered that I can simply initialize the table as such:

  float pp [100];

  The problem is that I find myself with a much bigger picture than what I need. I want to do is something like:

  float [n] pp.;

  where n represents the entry of an array size in the form node or is something like:

  n = sizeOfDim(td0,0);    Here I use a table 1 d

  None of these methods seem to work. How do I initialize my picture 'pp' such that it matches the length of array 1 d of "td0?

  The more likely your initialization externally.  Create an entry named pp and wire td0 inside as well.  Now create an output with the pp even name and it will contain an array of the desired length.  Of course, this assumes that you want to edit all items in pp.  Otherwise, just use initialize the array to create a new table and feed in the length of td0, and whatever default value you want (ie. 0 or NaN).  The blank values will keep this value after the node of the formula.

• using the formula node array index

  Hello

  I'm new to labview...

  I am creating a vi that takes a number n and out the primes from 0 to n (i.e. including 1).

  My approach to do, he uses a formula node, but I can't understand how the table index or for each number first output.

  It seems that my indexing algorithm works very well, but I'm just pushing it into the array as an element.

  It'll will be great if someone could take a look at my vi and give me a hint on how to index properly.

  Thank you

  your output should be a table and index first use [index]

  also you have to declare the index and Prime]

  

• whites in the data in the table using the formula node

  I have 2 tables 1 d of data go into a loop. Inside the loop, there is a formula node that combines the 2 sets numbers and did a little math for them. If the result of the calculation is 0, it means that the value is not valid. Nothing other than 0 is good value. The result of the calculation comes out the knot of the formula and leaves the loop becomes a table 1 d. Then my table is saved in a spreadsheet. 0 really screw up my graphics, and I want them to just be white instead. I tried to use NaN instead of 0, but who also live up to my graphics. How can I place white on the output instead of 0 array?

  It seems that your real problem is to define what will make Excel leave gaps.  For LV NaNs graphics to do what you want.

  You can also consider getting the output array an array of strings. There may be string values (NO?) that cause Excel jump.

• Sorting table 2D using the formula node

  Hello

  • What l am trying to do is kind of numbers in groups.
  • A group consists of the numbers that are equal, or step upwards or downwards by a single value. Each group must be assigned to a column. E.g. O column of the table of entry test would consist of 5, 4 and 3, but not the 9 and 10. These values belong to column 1. However if the adjacent cell in the column was not empty then 9 and 10 would stay in column 0
  1. To better understand the programming formula node went to 1 d. I found that each cell is not treated individually with my code.
  • The final table of the orange entry test is that the data type l want to sort a 2D picture that ends up the same size chart.
  • In the code l provided my goal to compare each cell of each column line to determine if a cell is equal for example a = b, a + 1 = b or a-1 = b If Yes, then these values are in the right column. If this is not the case, a sort must be made to put a value in the right column it is.

  This is my first shot with node formula and l must admit others examples l found a bit confusing how a result has been obtained. I prefer to do any programming in labview instead of going to another program for results l am after. I tried to picture of programming just for this problem and found to grow big and very complicated then stopped l. For me the road to node formula should be simpler and more compact. My last resort is to use Excel but l still hope to do all the programming in Labview l you end up with a more dynamic program.

  Hello

  You are brilliant... bloody!

  I just couldn't she would repeatedly using tables, l have been on it for weeks. I never thought about how you solved this problem.

  I hate excel and text. I am graphically spirit therefore l such as labview.

  I had a solution in Excel yesterday, but your solution is much better than what l came with

  I'm very grateful

  Thank you

• Need help on how to create the transformation of the Park by using the MathScript node?

  Hello

  I want to generate a transformation of the Park by using the MathScript node. But there is an error message which confused me. Please can someone help me to have a look of my program? Thank you!

  The error message is "error-90011 occurred in error in the function mail to line 1.  The sizes of the input matrices are incompatible.
  Check that the matrices have the same size or one is a scalar.

  Possible reasons:

  LabVIEW: Sizes of the input matrices are incompatible.  Check that the matrices have the same size or that one is a scalar".

  Hello

  The problem is that all of your entries to the MathScript node are vectors.  All entries of the vector to the MathScript node becomes vector lines.  A multiplication of two vectors lines generates a size mismatch error.  If you really want a scalar of this multiplication of output (by calculating the dot product of vectors), then you have to bring your 'a', 'b' and 'c' vectors or your vector of 'x '.  If you want everything just multiply your elementwise vectors and produce an output vector, you must use the elementwise multiplication operator '. *' (time point).  Use this operator between your 'a', 'b' and 'c' vectors and your calculation of fishing.  For example, on your first line,
  d = (2/3)*a.*(sin(x))+(2/3)*b.*(sin(x-(2*pi/3)))+(2/3)*c.*(sin(x+(2*pi/3)));

  Don't forget to also change your output to a 1 d of DBL array variables.  You can do this by right-clicking on the output variable and selecting "Choose Data Type."

• 30.0 Firefox is so slow since updated. IE & Chrome not having problems loading pages, showing the blank pages, need two or more tests to open Web pages.

  30.0 Firefox is so slow since updated. IE & Chrome not having problems loading pages, showing the blank pages, need two or more tests to open Web pages. It seems to have something to do with the Visual data on the pages. My MSN homepage gets old and dies every time I open the page after the re-opening and closing of firefox. It takes forever! What is a memory drain? Each open page in a new session of firefox suffer the same fate.

  Start Firefox in Safe Mode {web link}
  While you are in safe mode;
  Press < Alt > or < F10 > to display the toolbar.
  Followed;

  Windows; Tools > Options
  Linux; Edit > Preferences
  Mac; name of the application > Preferences

  Then Advanced > General.
  Find and stop using hardware acceleration.

  Dig safe web sites and see if there is still a problem. Then restart.

• Outputs not used in the formula node

  Hello

  To clean up my code and avoid repeated calculations, I want to use intermediate variables in my code formula node. To create those variables, the only way I know is to create an output variable of the node, which of course eventually unused. Y at - it no problem/inneficiency created by doing this?

  Thank you

  Define a variable inside the node form. Use the syntax of C

• applying the delay in the formula node in labview

  Hi all

  If you have not yet done so, please go through the tutorials free online on LabVIEW.

  Rarely is the node form the best way to write code in LV native LV constructions can be a little awkward at first for someone with programming experience text.  Once you learn how to use the stream and recognize functions by their icons, you can see that the graphical programming can be powerful and easy to read.

  For delays using the function Wait (ms) in the palette of Timing.  If you need a delay in the middle of a calculation (which seems unlikely), you may need to separate the calculation into two parts and put forward (ms) between the parties.  See the image below for a way to do this without no nodes formulas.

• a stop time loop by using the time difference of two counts of ticks

  Hi guys,.

  I'm writing currently a code test how much time does it take for a formula node perform its operation. The program uses some time to perform the calculation in a loop, and the program stops after having calculated when the number of cycles reached 10 seconds. The program then displays the number of iterations, he does it in 10 seconds.

  If at the beginning, I created 2 images of the structure of the sequence. In my first image, I have my original number, and as part of my second, I have my final number of cycles and the while loop. I used the subtraction function and divide the result by 1000 to get jet lag. Then using the comparison function, I put if output > 10 then the program must stop, to do this, I've linked out of the comparison function to the button stop inside the while loop.

  However, when I tried to run the code, the program just didn't run. That's why I created a similar program that puts the final number of cycles in the new image sequence. When I ran this code, the program never stopped.

  Guys do you have any idea what was wrong with my codes.

  Thank you!

  In the two VI the Terminal stop of the while loop is controlled by a Boolean value whose source is outside of the while loop.  If this loop will be executed once, or forever, depending on the value of the Boolean value which is calculated before the loop starts and comes to the tunnel through the loop.
