• Create table 2d by pulling larger 2d table columns, as indivated by an array of Boolean

  Hello

  I have a 2d chart with 16 columns that contain data from different input channels.  I also have a 1 d array of Boolean (length 16) corresponding to these columns.  In the table of Boolean 1 d, if a value is true, I want this column in table 2d to stay.  If the value in the table of Boolean 1 d is wrong, I want to delete the corresponding column.

  Thus, for example, if the table of Boolean 1 d looks like this:

  [T T T T F F T T T F T T F F T F]

  the new 2d array would be 10 columns, which correspond to the columns of the old 16-column of table 1, 2, 3, 4, 7, 8, 9, 11, 12 and 15.

  I am very new to labview (programming just started yesterday). Can someone help a newbie to do something that is probably simple? In my view, that there will be an iteration back through the deletion of rows and 16 columns table columns as they come if the value of the Boolean vector is false, or iterate forward through the 16 columns and add columns to a table if the value of the Boolean vector is true... but I don't know how to do this.

  Thank you

• ASC file in 2D array of Boolean

  Hey guys,.

  I was wondering if there is a method to download a *. CSA or *. DAT file to convert it to an array of Boolean 2D.

  For example, I would create a .asc or .dat file composed of strings using MATLAB to generate

  1 1 0 1 1 0 1 1

  0 1 0 0 1 0 0 1

  1 0 0 1 0 0 1 0

  and it would be to convert the string to an array of Boolean 2D of

  T T F T T F T T

  F T F F T F F T

  T F F T F F T F

  while I can ultimately use it to create a digital waveform graph changed like this:

  

  The goal is because I use the sampling frequencies of 0.1 second interval that spans 2-5 minutes.

  So to summarize:

  1. download a *. CSA or *. DAT file with a 2-D array of strings

  2 convert the file to create a Boolean matrix 2D to use create digital waveforms

  Any help will be appreciated. I know it's not much but I downloaded the table 2D to waveform *.VI for testing purposes.

  sdkpark wrote:

  However, when I tried first, he doesn't know how to separate each column in the *.asc file

  1 0 0 1 0 0

  0 1 1 0 1 1

  It turns out only to read the first column

  Please attach your VI instead of an empty image of sense.

  Reading spreadsheet file will read all the data if used 2D correctly. The defined delimiter is separating the elements and line break between the lines. For example, if you do not wire the delimiter, it will assume "tab" and that a single value is read by line if it's actually a space character. Try a delimiter of the 'space '.

• Random 2D array of Boolean

  Thank you

  Table initialization function will give you the same value for all items. It is documented in help. For example, you cannot use this way. You can simply use two loops so you generate a random number for each element of your 2D array. I do not understand what you say about the number of table of Boolean, or why you using same. If you use the 2-loop approach, all you need to do is decide what you consider a "1". For example, you might say that something greater than 0.5 is a '1 '. This can be done with a single superior? function. Note that this should be done inside the loop.

  An alternative is to use the continuous random function to obtain an array of random numbers that you can remodel in a 2D array. You must decide if the distribution provided by this function is "random".

• generate the subset of the decimal table to an array of Boolean

  I have a decimal table 1 2 3 4 5 6, and I have a boolean with the same table size 0 1 0 1 1 0.

  How can I retrieve the subset of the decimal table of the corresponding "1" position of the table of Boolean (in this case 5 4 2)?

  The value of the Boolean table are editable (casting either 1 00100), so the size of the array decimal subset is not fixed (1, 4).

  (I assume you mean digital Board. "Décimal" is just a specification of formatting and irrelevant for this)

  Try something like the following (the FALSE case has just wired table in the whole unchanged):

  

  (In case you're dealing with huge paintings, a few performance modifications should be made so that everything goes more in place.)

• How to select cases or an event using an array of Boolean 2D.

  Hello world

  I'm trying to use an array of Boolean 2D to select different events or case. For example, if the variable Boolean 1 and 2 are TRUE, case 1 will be selected. If the Boolean variable 1 is FALSE and 2 is true, case 2 will be selected and so on. I tried to use the Boolean to the number, but I need a way to differentiate between B1 = B2 = FALSE and B1 = B2 = TRUE, FALSE, TRUE. In other words, no two Boolean combinations can lead to the same case, seminar.

  ~ Mario

  You need to remodel your table 2D to 1 d first.

  Now, assuming that you have the items in table 64 less thant, "boolean array to the number" will give you a unique number for each possible combination of bit.

  As mentioned, each combination will give you a different value. You must simply ensure that you Add unique cases for each number. Add as many cases you want to structure your business. If you do not, several models of trigger default case-sensitive.

• Through the sum of the values in all of the array of Boolean one and zeros

  Hello.

  I have an array of Boolean which I have converted one and zeros. I just want to the sum of all the elements in this table (in other words, giving the number of 1 in the table). I used the feature to add items, but I get a negative value. I checked there were not all values except one and zero (I know it shouldn't be) using max and min. I don't know how a negative value has been calculated - any ideas.

  Thanks in advance

  Before adding elements, convert the table I32 or I64. The output of the primitive add-on is of the same type that the entry and if the entry is an I16, then you cannot have a value greater than 32,767 or value will wrap around (what happened in your case.

• Use an array of Boolean to jump to sections of code (extensible design).

  I currently have four pieces of code (which could turn into 5, 6 or more pieces in the coming months), I want to run or jump selectively according to an array of Boolean.  I have a cluster typedef of numbers, which are each refers to a port VISA number connected to a particular instrument.  This will be expanded in the future as the software is necessary to control the instruments more.  There is an array of Boolean (coming from the vi) attached which has a value of TRUE for each instrument that was detected (and therefore is connected).  In the case below, I want to initialize each instrument that is connected, but not try to do something for those who are not.

  The cluster and the Boolean chart is shown below:

  

  As someone who will need to expand in the future on this section of code, I want to write it in a way that will be infinitely extensible, without taking more space BD.  At the moment I find myself unable to do since I do not know how to pair the table of Boolean with the elements of the bunch, such that I can run or ignore the code accordingly.

  Help, please!

  -James

  Since you mention that you want to expand, I'd be more inclined to set a dashboard containing the port number, the type of instrument and the status of the instrument. When you search for your instruments you want to iterate over the array. You can use an ini file to determine which instruments must be present in the system. Others may be optional, and their associated actions could be ignored if necessary. However, the main point I'm trying to do is to combine your status with your instrument information table. This way, you eliminate the possibility of a mistake trying to keep and table and a synchronized cluster. A table makes it also much easier add or remove instruments from your system.

  A few other notes, if you check in a stop condition then stop. Don't simply continue the execution of each iteration of the loop with a business structure that will jump execution if the stop consifition is encountered. Simply stop. Imagine if you had 1000 items in your instrument cluster/table. Using your method always run you your loop 1000 times, even if the shutdown occurred during the first iteration. Eliminate duplication of code and logic twisted to combat it. You have two places incentive th euser, if they want to start or stop. You must have a place to make this code. Much easier to understand and maintain. Don't expand your code easily either because the hard-coded error strings. Your case statement will become very large if you generate your static error strings. Use a loop and a format common you build your missing channel of the instrument. If you use the table on the groups of instruments, I suggested that you will be able to format the string using the type of instrument. I'd be much more inclined to use a single notification utility that will be supported as well cancel and stop messages. It changes a lot better when you have additional message types rather than use a notification for each type of message.

• Is it possible to an array of Boolean function number in a case without the table of Boolean structure?

  Hi guys! In my program, my "robot" (lego mindstorms EV3) has essentially read a code bar and do different things according to the codes bar, he reads and so I have an array of Boolean, and basically I need compare to the other Boolean tables. First of all, I used the "Boolean chart at number" function and then just put it in a structure of the case, but it turns out that the Boolean value to number function is not compatible with my Lego EV3 brick, so I have to find another way to do this. Any ideas?

  Help is appreciated! If you have any questions or if my question is confusing, just ask!

  Thank you.

• How to create dynamic arrays parallel/side-by-side in Adobe cycle

  Is it possible to create dynamic arrays parallel/side-by-side in Adobe cycle?  If so, how?

  Given that the tables have different sizes, in that I am running wrapping issues with running adjustment of Western characters and characters from the pagination with checkpoint.  Any other ideas?

  In fact, I had tried this solution ("wrapping the tables in a subform of position and set to automatically adjust the height and allow page breaks"), but it did not work.  Something to do with nested subforms of position within a subform control flow etc.  So to make it work, I set the page to be a subform of position and the auto-hauteur value and allow page breaks and I unpacked the paintings while they were only 'wrapped up' of the page itself.
