Extend the two-dimensional array

Hi all

How can I extend both the axis of a two-dimensional array?

DECLARE
  TYPE num_array IS TABLE OF VARCHAR2(100);
  TYPE bidim_num_array IS TABLE OF num_array;
  l_array bidim_num_array;
BEGIN
  ...
END;

in order to fill the two-dimensional table as a matrix:

l_array(1)(1) := ...
l_array(1)(2) := ...
l_array(1)(3) := ...
l_array(2)(1) := ...
l_array(2)(2) := ...
l_array(2)(3) := ...
l_array(3)(1) := ...
l_array(3)(2) := ...
l_array(3)(3) := ...

I don't know the size of the MxN matrix.

Thanks in advance.

Just as you would with one-dimensional, just twice - one for each dimension. You will also need to initialize second dimension table whenever you extend first dimension:

How to extract a single dimension of two two-dimensional array

Hello

Perhaps this question is too naïve and simple. I have two two-dimensional chart (256 rows and two columns). All I want is to retrieve one of these columns as a dimensional table a separate. It seems to be something very very basic that should cover just about any programming language. However, I couldn't find the right function in the list of functions of table. I don't know I'm missing something very obvious. I tried the Board index, subset of table, table of cluster and reshape the table. None of them is the right function for this. I have used LabVIEW for awhile now, but I can't find a solution to this fundamental problem. Can someone help out me.

Thank you

HI -.

With the function Index Array you tried a number of cabling to the marked entry index (col)?

See the vi attached for an example.

Problem of two-dimensional array
I have problems assigning values to two dimension table. Here is an example:

_Global.test = new Array (new Array, new Array);

for (n = 1; n < = 3; n ++) {}

_Global.test [n] ["txt"] = n;

trace (_Global.test [n] ["txt"]);

}

Here is the trace output:
1
undefined
undefined

Can someone please tell me what I'm doing wrong?

Easy way to extract the line of two-dimensional array?

Y at - it an easy way to extract a two table row Dimensions? I have two lists of table to a dimension that I consider a pine table, where each pin list is a table of numbers. I want to go through it and to extract a line at a time to send in a vi. Currently, I'm looking to do a bit of a long way, and I was wondering if there was an easier way. The long way:

GetArrayBounds (Locals.ArrayOfPinsToTestAtOnce, Locals.BogusString, Locals.ArrayBounds), / / enter the quantity of lines and columns Locals.ArrayBounds

Locals.ElementsPerList = Val (Mid (Locals.ArrayBounds, 1, 1)), //Get number of bowling by list

Locals.NumberOfLists = Val (Mid (Locals.ArrayBounds, 4, 1)), //Extract number lists

SetArrayBounds (Locals.OneRow, "[0]", "[" + Str (Locals.ElementsPerList) + "']" ") //Set table defines for a line chart

< locals.numberofgroups;="" i++="" )="" would="" be="" done="" in="" teststand="" step,="" just="" for="" easy="">

{

    < locals.elementsperlist;="" j++)="" also="" would="" be="" done="" in="" teststand="">

        Locals.OneRow [j] = ArrayOfPinsToTestAtOnce [j] [i]

    PERFORM STEP HERE (Locals.OneRow)

}

Thanks for the tips!

In all honesty, I just want to do in LabVIEW. You can try to add to the list in this idea.

with 2 collar and two rows two-dimensional array

I could not find how to form a matrix 2 x 2 in the old Easter in ActionScript. All bays are only a single line. How can I change it.

var myArray:Array = new Array();

myArray [0] = new Array (val1, val2);

trace(myArray[0][0]); val1

trace(myArray[0][1]); val2

But depending on what you actually trying to do there may be better ways. For example, if you save to x and plotting perhaps.

myArray [0] = new Point (val1, val2);

trace(myArray[0].x);

trace(myArray[0].y);

Or you can push an object in the table. Or even use a vector...

How to keep account different values of two two-dimensional array

Hello

I need help regarding one of my LabVIEW VI. I have three matrices 2 dimensions, namely Sx, Sy, and P of dimension 4 x 4 of each. I want to do the following calculation:

P(i,j)=[P(i,j+1)+P(i,j-1)+P(i+1,j)+P(i-1,j)]+1/8*[-3*SX(i,j+1)+SX(i,j-1)+2*Sy(i-1,j)-2*Sy(i+1,j)].

For now, you can consider all values of Sx and Sy matrices and matrix P for the first time for all the elements as zero.

I did it in Matlab, but have no idea on how to do this in LabVIEW. Please help me in this regard.

Thanking you!

Two dynamic arrays

I have two dynamic arrays in my form. Each table dynamically sizes based on pressing add or remove buttons. However, the first table develops in the other table. I can't place the two paintings in one as the purchase order example because after the second table I have text and additional fields... If the two tables must expand the page to explain the additional lines. Any suggestions on how to link tables to account for the other and additional text fields?
Thank you

Hello

You can go there. The main problem is that the subform parent (page1) has been defined place and has not sunk). It's working now, but there are form elements you want to put in a positioned subform.

Basic approach should be:
- Form design using initially positioned subforms.
- Wrap the form objects that don't grow in positioned subforms (for example, it is objects that are side by side in a group that don't change position or size compared to the other);
- You may find yourself with several subforms positioned;
- Then wrap the dynamic objects (those that increase in size or addInstance) in subforms flowed. Yet once, there may be a few of these intercalated between positioned trees;
- Last step: set the subform parent to slur. At this point, things will be moving around the shape and you may need to change the subforms flowed to get the look and feel right.
Basically, that's what I did with your form (with the exception of teaking in good standing objects).

I hope this helps,

Charger property - number of one-dimensional array objects read

Greetings and happy independence day.

I use the property Loader to load a local array of containers. I use a ForEach statement to iterate through the array for the number of items varies with the type of the object to measure.

But now, I need to know how many items is in the table before starting this treatment. I could scratch a local variable and pass through a preliminary ForEach to browse it upward. Is it a better or easier way to do this?

Thank you

Comparison of the elements of the two 2D arrays

Hello!

I am trying to compare the elements of both 2D and find at least one pair of elements that are identical. Browsing the forum I found a method suggested by Altenbach (http://forums.ni.com/t5/LabVIEW/Compare-elements-in-an-array/m-p/458622). However, it works well with 1 d arrays. That's why I rearranged the original code for my case, but unfortunately the attempt failed. Could someone please take a look at my VI and suggest a solution?

Thank you.

5 is correct. Create indicators for arrays of I32 2D coming out the loops with the table inside the cluster. On line 1, column 0 on both of these tables, you will find the value 5. That's what generates your code, but it is probably not what you want.

Look at what I added at the bottom of the BD, the 2 identical and identical on the FP Indices.

Selection of one-dimensional Array objects in a hash table

Suppose I have a hash table with a list of names of virtual machine. I also have a variable array containing objects of virtual machine and all of their properties. I want to scroll the array variable and delete all virtual machine names that do not exist in the hash table. How do I would accomplish this?
Thank you

If your table is called $inArray and your hash table is called $hashTab, you could do something like that

$outArray = $inArray | %{

If ($hashTab.ContainsKey ($_.)) VMName)) {}

$_

}

}

The selected objects will be $outArray table.

Temporary Tables vs. two multidimensional arrays
Dear gurus,

We have an obligation to perform a loop on a few thousand lines and do some calculations complex (to do in PL/SQL cannot be through simple SQL). These lines came out of a long running query dealing with millions of rows.

Now the question - our team is to have a confusion if we need to use a temporary table or tables in two dimensions.

We tried both ways and right now, there seems to have not much of a difference in processing times. (I know it's not good to be based solely on the processing time, especially when it is just a test environment - not as much data as in production, diiferent server,...)

Could you gurus please thow shed some light on this? The use of memory other resources the same in both cases?

Thanks in advance.

No PGA. Oracle will use the temp space (shareable) database.

Save two-dimensional image od for the web

Hello
I made the script (with your help ) to export images for the web with dimensions 300 x 300 px. Now, I want my script to resize more than files that I get two files one 300 x 300 and another 66 x 66 px. I'll post my script and you ask hel find me the bug
And another question. My script exports the file name + jpg, but it also keeps orginal extension if I get IE. FileName.psd.jpg
can you help me solve this in my script... else is very well...
Thank you

sum on two dimensional

Hi all, I'm fine with excel, but have trouble extrapolating numbers for this and hoping that someone can help.

Basically, for example, a spreadsheet to budget domestic. I have a table of data where column A is the month of the entry, column B is the category, and column C is the $. Something like:

A         B                   C

April 1 grocery store $100

2 April gas $50

grocery store $75 April 3

May 4 utilities $50

grocery store $90 may 5

May 6 gas $40

(imagine the above, but with several months of data).

I want to create a summary table summarizing the totals by month and category

A                   B                C

April may

Food products 1 175-$ 90

2    Gas                $50             $40

3 utilities $0 $ 50

That means, in B1, the sum of $ is the $ total for all groceries in April entries in the table above ($100 + $75).

My excel formulas do not seem to be transferred on the well, when I try to build it. Any ideas? What is quite a unique use of SUMPRODUCT in numbers or something else?

Thanks for the thoughts that you all.

See you soon,.
Aaron

The numbers do not support forms of 'matrix formula' of SUMPRODUCT. Use rather SUMIFS (which also works well in Excel).

The formula in B2, filled with worms the down and right, is:

= SUMIFS(Data::$C,Data::$A,B$1,Data::$B,$a2)

Be sure to type a "before names so that the numbers treated as text and you will get a match." Otherwise, it will guess that you mean a date and time string (which will match this year, but not for the entries of entry next year).
