kandi X-RAY | array2d Summary

array2d is a Rust library typically used in Big Data, Numpy applications. array2d has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Array2D provides a fixed sized two-dimensional array. It is more efficient and is easier to use than a vector of vectors, i.e. Vec>. This is beneficial when using a grid-like structure, which is common in image processing, game boards, and other situations. Array2D cannot be used when rows or columns might have different lengths⁠—all rows and columns must be the same length.

How to get next element in for loop in javascript

In a dataset I have different locators. Some places are free (locator = null). I would like to capture these and push them into arrays.

In the subarray may only be locations that are in a row. If a distance is greater than 1 then it comes to the next array.

Reading and writing two-dimensional array to file

Asked 2021-Feb-12 at 11:22

I get a 2D array from a device at specific time intervals. I keep these series in a list. I need to write the sequences in the list to the file on the computer. After reading these series I will put it in the list again. I found a method for this. I can write the series. I have some questions at the point of reading.

When I write a fixed array; Example short[,] array2D = new short[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } };

I read it properly when I want to read the same series knowing its dimensions.

But when I write more than one series in a row, I want to read it piece by piece. I failed on this. How can I read the sequences from the file?

Write Code

The problem was so simple that I don't know how I missed it. The array type I defined during reading is integer, but my data is short. When the data type of the array was short the whole problem was gone.

I also solved the total number of sequences in the file as follows.

The lengths of the 2-dimensional array at the time of writing are 48 * 64. I divided the total number of bytes in the file by 48 * 64. Also, since my data is short (2 bytes) I divided it by 2 to get the total number of strings.

Creating then printing 2D array - print problem

Asked 2021-Jan-21 at 08:58

I've got 2 functions. One to create 2D array, the other to print it. Something is wrong with the creating function, because when I create and send an 2D array by myself, everything is fine. But when I try to do this through the create funcion, the console is empty (but no errors). Could you help me?

ANSWER

Answered 2021-Jan-21 at 08:57

The problem is that you don't create a 2D array as far more a 1D array.

In each iteration step you have to create an array and push it to your array to create a 2D one.

Use !includes() to exclude both Summary and Result sheets.

as you can see, index m represent outer index, i represent the inner

array2d[m][i] = 2; character.x = i; character.y = m;

however, this console.log statement use i(character.x) as outer,which will be more than 6 to make it undefined

console.log(level0[character.x + 1][character.y]);

then undefined[m] will be uncaught type error

Script to VLOOKUP Summary Column From Multiple Tabs Pull Data wrt Value From Each Tab

Asked 2020-Dec-08 at 15:19

I've a sheet where there are multiple tabs. I want to summarize first column and 11th column of all tabs. I would like to merge the first column so there are only unique values. Then pull the data from first tab as 2nd column and second tab as 3rd column and so on. The sheet is here

What I've tried so far: I have tried to use formula which is both manual and ever increasing. The tab name is "Desired". For the first column I used query formula. I used only for two tabs since I've more tabs.

ANSWER

Answered 2020-Dec-08 at 15:19

You could do the following:

Get the headers of the destination sheet, starting with Company Name and followed by the different sheet names.
Get the unique names of the companies (2D array with inner arrays having a single element - the company name).
Iterate through all sheets ending with 2020. For each sheet, follow steps 4-5.
Iterate through all rows in the sheet. For each row, look for the index of the company (column A) in the array of companies from step 2, using findIndex.
On the index found in 4, push the value from column 11 to the corresponding inner array (from step 2).
Concatenate the headers from 1 with the values from 4-5.
Since the different inner arrays have different lengths, find the array with maximum length and add elements to the others so that all inner arrays have the same length (that's necessary when using setValues).
Use setValues to write all your summarized values to your destination sheet.
