NaN values in table

• How can I delete a table NaN values?

  I'm testing if an array values are less than 0.001. They are all... BUT the problem is that some of the elements of the array are NaN values. I want to do two things:

  1 remove NaN of the array elements and put them to zero to make the test work.

  2 to understand that NaN elements are tested.

  The results in an array of Boolean values of T, F. If all the values of the boolean chart are T, resulting in a single Boolean value of t. # 2, I I want to test if an element of the array is less than OR equal to 0.001 NAN.

  Various positions have been in the past to the deletion of items in a table. I'm sure that you took the time to research before you posted, right? In any event it seems not that order is important here, so the best way to proceed is to sort the array and then search for the first occurrence of NaN. Just do a comparison on the subset of the front table of this index.

• Analysis.Math.Statistics fails when NaN values are included in the entry tables

  Hi all..

  With the help of Measurement Studio to Version 8.9 of .net. We need calculate statistics on a table that contains a double. NaN values. When I do this I get NaN as the result of any of the statistical methods (average, STDS etc.) ... Interestingly, the Math.ArrayOperations methods look like they work. Any ideas?

  Thank you

  Hi GDSSoftware,

  You see this behavior because the statistical functions with Measurement Studio ignore not input values NaN - that is why, they will return results NaN.  To work around this problem, you will need to filter these NaN values out of your input array before performing statistical analysis on this subject.

  If you're working with .NET 3.5 and later versions, you can do this by using the following:

  Double [] vals = new double [] {0d, 6 d, 10 d, 4 d, double. NaN};
  Double [] nanless_vals = vals. Where (d =>! double.) IsNaN (d)). ToArray();

  If you use an earlier version of the .NET framework, you will need to perform a loop on the table with the following (or something similar):

  Double [] vals = new double [] {0d, 6 d, 10 d, 4 d, double. NaN};
  List nanless_list As new List();
  for (int i = 0; i)< vals.length;="">
  If (! double.) IsNaN (vals [i]))
  nanless_list. Add (Vals [i]);
  Double [] nanless_vals is nanless_list. ToArray();

  I hope this helps!

• Anova 1 d return NaN values

  I have this vi, in which I want to use an anova 1 d, but I always get NaN values. I tried the example here: http://forums.ni.com/t5/LabVIEW/1D-ANOVA/td-p/702716/page/2, but I still can't make it work.

  Can someone help me please?

  Thank you.

  The table connected to the entrance of the ANOVA.vi D 1 index contains only zeros. Your case statement strange within the structure of the event, which always adds 1-1 regardless of the value of i is a specific candidate for the thread code Rube Goldberg.

  You have a lot of duplicated code, fan, hard to follow the wires twisted, and records the unused shift.

  Do not use the button abandon to stop your VI. Place a Stop boolean on the front panel and it wire end of the Terminal loop. It is not considered polite to postal code with infinite loops.

• Dynamic assessment of value of table

  I have a table that holds the rank 7 rows, with each having about 20 objects and respective values - these values correspond to checkboxes and comboboxes in the flex application. I want to be able to do is to loop through the array and retrieves the values without having to hardcode the array element, I try to access - this is what I try:
  
  for (var i = 1; i < 7; i ++) {}
  var tempTerm = "wopTerm";
  If (classValues [temp] .wopTerm + i! = ") {}
  This ["wopCheck" + i] .selected = true;
  This ["wopTerm" + i] SelectedIndex = classValues [temp] .wopTerm + i;
  This ["wopPrcnt" + i] SelectedIndex = classValues [temp] .wopPrcnt + i;
  }
  }
  
  the value 'temp' is a selected index value so I don't know that the rank of the array to access, based on the value selected in the combobox (an entry is selected, then the goal is of check boxes and select the combo box items based on the values in the table). If I 'i' replace with a number (losing the concatenation symbol) it works fine, but I want to do it in a loop to be more scalable.
  
  When I run the page, the statement returns the NaN value instead of the value in the table. Any ideas?
  
  Ethan

  You should know that obj.abc is equivalent to obj ["abc"], which allows to work with strings when you reference properties. So you should do this: classValues [temp] ["wopTerm" + i].

• Indexing of typical BINARY_FLOAT NaN values

  I'm indexing NaN values for a column that is BINARY_FLOAT types, but it does not use the index for NaN values - but it will use the index for non - NaN values.
  

  create table nan (id binary_float) ;
  
  begin
       for x in 1 .. 10000
       loop
           if ( mod( x, 10 ) ) = 0 THEN          
             insert into nan values(x) ;
          else
            insert into nan values(binary_float_nan) ;
         end if ;
       end loop ;
       commit ;

  I tried to use a trick, but I get the same result.
  Select / * + INDEX (n, nan_id_i) * / nan id n where id is nan
  
  But it will use the index for values of non_NaN:
  
  Select the id of nan where id = 20;

• How to compare the original value of table size and the changed value

  juice I took a table and then took the function of the size of the array so that it shows me the number of the elements present in it. so it'll be the original table size value.

• Values discrete table slide

  Hello. I have a 1 d array of double for example [1, 2.5, 3, 6,8, 10] and I would do a regulator to behind the scenes, where the user can choose only those exact values. Please note that this example vector is very low and in fact I vector 'time' it had been longer, 100 numbers, so some manual Insertion is not an option .

  I have already searched in 'property node', but did not find anything useful.

  Thank you in advance.

  The table is always sorted?

  You could use "threshold" with the value of your slide and the table of valid points sorted, round off the result to the nearest index, then use the table to index to get the valid value for further processing.

  You can also subtract the value your table silde, take the absolute value of the result and use table min & max to find the index of the closest point.

  Once the slide is released, you can write the valid value back to the slide (don't fight the user when it is running it!).

  A better solution would be to use a whole blade where each value is the index of the array element. Hide digital display and scale and show the value of something that looks like a digital display, but is actually a separate indocator.

• Obligation to fill the values in table advanced according to the selection of a value in another article of lov (not in the advanced table)

  Hi all

  We work in a custom oaf page subdivision. We have an obligation to fill the values in table advanced based on a value selection in an element of the lov (this LOV is not in the advanced table) .can share you it please me steps or examples of code to achieve this. Waiting for response.

  Kind regards

  I do not understand completely still. What do you mean by "default in the table values must be inserted".

  You can create a dummy VO with the same columns and fix the VO in the advanced table.

  In the normal scenario, when the user clicks on submit button, browse this VO, and copy the values to the validation according to VO and appeal EO. If values gets inserted into the database.

  When the user selects the number of PO, simply run the other VO and fill this dummy VO so that values are available in the advanced table. When you click on send, do not copy these values to the EO based VO, so these lines won't get inserted.

  It work?

  See you soon

• Report header update XML with values of table of process model

  Using Get and add steps to add some containers StationGlobal the XML report.

  

  Then made changes to the horizontal.xsl to show the new values.

  

  Everything was fine until I tried to view the news of cable that is a container for three tables.  Find the correct xsl to analyse the way in which the table is stored in the xml file throws me a loop for.  Joined a scale to the bottom of the example.

  How the XML is stored...

  

  my best attempt at analysis... that it performs a loop twice but displays the same results

  

  Any thoughts...

  Thank you

  I have attached copies updates to your XML and XSL files. Please take a look and see if this implements your target. Let me know if it does not or if you have questions about the changes.

• Under certain conditions add value in table

  Hi all

  I have two tables 2D of the string data in my VI (taken from the .mdb using ADO & SQL file). The "Window list" table on the left, that's what I want to add values to. The 'List of glass' table on the right contains the values that I want to add to the main table according to the values in other cells.

  For example:

  1 component ID window are 2191 and 2001. Under the thickness of the component 1/component 2 in the table "window list", I would add the thickness appropriate for stream ID 2191 and 2001 table "list of glass".

  Here's a snip of the two tables in question.

  This should be simple enough, but as I am a rookie LV I am not very well how to do.

  Thank you very much

  Laura

  

  Joint must be what you want.  Let me know if you have any other questions.

• remove the threshold values of table

  Hello

  I would like to get help to complete my program where I am removing values above a threshold in a table and establish the curve according to the values above the threshold (from-45 in this case) is deleted.  I still seem to have a few values greater than the threshold that appears in the desired graphic.  Any help is greatly appreciated.

  Your VI is extremely complicated. All you need is a conditional tunnel.

• Reset to the values in table

  I built a VI which I think must initialize an array of bool 8 element to all WRONG. Then at each iteration of the for loop, it is, should turn each element increasing to TRUE. But in each iteration of the loop, the item previous returns false instead of stay TRUE. Why is this, and what logic is necessary to avoid this problem?

  dourk wrote:

  I added the shift register, and if I run it without the DAQ help, it works perfectly, thank you!

  You must use "replace table subset", "do not insert in the table". You will also need to initialize the array with 8 elements.

  ("insert into array" will grow the array by one element each time you insert one, move everything higher up. After two iterations, the table will have 9 items. However, 'replace table subset' will keep the table the same size, by changing the value of an element by a new value)
