The intrinsic pack function packs an array into a vector, selecting elements based on a given mask. The function has two forms PACK(array, mask) PACK(array, mask, vector) (that is, the vector argument is optional). In both cases array is an array, and mask of logical type and conformable with...

To get the next element you can use the .next() method. <ul> <li>Mark</li> <li class="anna">Anna</li> <li>Paul</li> </ul> If you are standing on the "Anna" element and you want to get the next element, "Paul...

Polymer prodives a lot of well built elements for you to use in your app. Browse them in their Element Catalog. Let's go through the workflow of using an element by including paper-input (Documentation) Download the Element To Download an element there are two ways: Bower The convinient way is...

We got the following very basic element my-element saved as src/my-element.html <link rel="import" href="bower_components/polymer/polymer.html"> <dom-module id="my-element"> <template> <style> /* local styles go here */ ...

In most examples, the class naming convention is used to define an Aurelia Custom Element. However, Aurelia also provides a decorator that can be used to decorate a class. The class is again treated as a custom element by Aurelia then. The value supplied to the decorator becomes the name of the cus...

let sel = document.getSelection(); let myNode = document.getElementById('element-to-select'); let range = document.createRange(); range.selectNodeContents(myNode); sel.addRange(range); It may be necessary to first remove all the ranges of the previous selection, as most browsers don't s...

In case you need to read an array elements avoiding repetitions you case use the #uniq method: a = [1, 1, 2, 3, 4, 4, 5] a.uniq #=> [1, 2, 3, 4, 5] Instead, if you want to remove all duplicated elements from an array, you may use #uniq! method: a = [1, 1, 2, 3, 4, 4, 5] a.uniq! #=> [1...

3 You can use rem defined by the font-size of your html tag to style elements by setting their font-size to a value of rem and use em inside the element to create elements that scale with your global font-size. HTML: <input type="button" value="Button"> <input type=...

To get the previous element you can use the .prev() method. <ul> <li>Mark</li> <li class="anna">Anna</li> <li>Paul</li> </ul> If you are standing on the "Anna" element and you want to get the previous element, &q...

To perform elementwise multiplication on tensors, you can use either of the following: a*b tf.multiply(a, b) Here is a full example of elementwise multiplication using both methods. import tensorflow as tf import numpy as np # Build a graph graph = tf.Graph() with graph.as_default(): ...

This example demonstrates how to place 3 buttons in total with 2 buttons being in the first row. Then a wrap occurs, so the last button is in a new row. The constraints are simple strings, in this case "wrap" while placing the component. public class ShowMigLayout { // Create the ...

For the example, lets say that we have a List of type String that contains four elements: "hello, ", "how ", "are ", "you?" The best way to iterate over each element is by using a for-each loop: public void printEachElement(List<String> list){ for...

All collection objects contain a map method that takes a Function as an argument, which must take a single argument. This returns an Iterable backed by the collection. When the Iterable is iterated, each step calls the function with a new element of the collection, and the result of the call becomes...

Often you need to change the way a set of data is structured and manipulate certain values. In the example below we got a collection of books with an attached discount amount. But we much rather have a list of books with a price that's already discounted. $books = [ ['title' => 'The Pragma...

A way to use confirm() is when some UI action does some destructive changes to the page and is better accompanied by a notification and a user confirmation - like i.e. before deleting a post message: <div id="post-102"> <p>I like Confirm modals.</p> <a data-dele...

It's possible to perform elementary set operations with Matlab. Let's assume we have given two vectors or arrays A = randi([0 10],1,5); B = randi([-1 9], 1,5); and we want to find all elements which are in A and in B. For this we can use C = intersect(A,B); C will include all numbers which ...

If your array or array-like object is numeric, that is, if all its elements are numbers, then you can use Math.min.apply or Math.max.apply by passing null as the first argument, and your array as the second. var myArray = [1, 2, 3, 4]; Math.min.apply(null, myArray); // 1 Math.max.apply(null, my...

To find the largest or smallest element stored in a vector, you can use the methods std::max_element and std::min_element, respectively. These methods are defined in <algorithm> header. If several elements are equivalent to the greatest (smallest) element, the methods return the iterator to th...
