Simple, Inline Equations You can do a simple inline equation by using $an equation here$. For example, you might do $\lim\limits_{n \to \infty} \frac{1}{2^n} i\bar z$ which, if we put a little fake text around it, gives Numbered, Centered Equations When writing papers or other documents, ...

Sometimes, it can be difficult to find the mathematical symbol you need. There are several options here. The first (and quickest) is to use Detexify, where you draw the symbol you'd like, and it tries to find what you want, like as shown below: Another option is to use the comprehensive LaTeX sym...

While standard LaTeX is all that is needed for most simple mathematical formulae and equations, sometimes more symbols and tools are needed. There are multiple packages available that will enhance your equations and provide you with more to work with. Three of the main packages are described below. ...

Let's say you cannot find the symbol you need anywhere. You can create a custom symbol. For example, the code \documentclass{article} \usepackage{graphicx,amsmath,amssymb} \DeclareRobustCommand{\diamondtimes}{% \mathbin{\text{\rotatebox[origin=c]{45}{$\boxplus$}}}% } \begin{document} $a\d...

Matrices You must always use the amsmath package if you are going to use the following commands. There are four main types of matrix, as shown in the code below: \begin{matrix} a & b \\ c & d \end{matrix} \quad \begin{pmatrix} a & b \\ c & d \end{pmatrix} ...

Possible values are Continue | Ignore | Inquire | SilentlyContinue | Stop | Suspend. Value of this parameter will determine how the cmdlet will handle non-terminating errors (those generated from Write-Error for example; to learn more about error handling see [topic not yet created]). Default valu...

//Add value to Isolated Storage Settings IsolatedStorageSettings.ApplicationSettings.Add("Key", "Value");

//Check if a value exists in settings already if (IsolatedStorageSettings.ApplicationSettings.Contains("Key")) { //perform logic }

string setting = IsolatedStorageSettings.ApplicationSettings["Key"] as string;

IsolatedStorageSettings.ApplicationSettings.Save();

By default, Jsoup will display only block-level elements with a trailing line break. Inline elements are displayed without a line break. Given a body fragment, with inline elements: <select name="menu"> <option value="foo">foo</option> <option va...

The gridspec package allows more control over the placement of subplots. It makes it much easier to control the margins of the plots and the spacing between the individual subplots. In addition, it allows for different sized axes on the same figure by defining axes which take up multiple grid loca...

This is a simple implementation of Binary Search Tree Insertion using Python. An example is shown below: Following the code snippet each image shows the execution visualization which makes it easier to visualize how this code works. class Node: def __init__(self, val): self.l_chil...

Package TikZ lends itself very well to drawing graphs. This is a small example (requires TikZ 3.0+): \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{positioning,arrows.meta} \begin{document} \begin{tikzpicture}[auto,vertex/.style={draw,circle}] \node[vertex] (a) {A}; ...

TikZ provides syntax similar to DOT which you can use to tighten up your graph drawing code considerably. \documentclass{standalone} \usepackage{tikz} \usetikzlibrary{graphs,quotes,arrows.meta} \begin{document} \begin{tikzpicture} \graph[nodes={draw,circle},edges={-{Stealth[]}}] { ...

TikZ implements several algorithms for automatic graph layouts (requires LuaLaTeX). \documentclass{article} \usepackage{tikz} \usetikzlibrary{graphs,graphdrawing,quotes} \usegdlibrary{force} \begin{document} \begin{tikzpicture} \graph[spring layout] { A -> ["1"...

Thorup's algorithm for single source shortest path for undirected graph has the time complexity O(m), lower than Dijkstra. Basic ideas are the following. (Sorry, I didn't try implementing it yet, so I might miss some minor details. And the original paper is paywalled so I tried to reconstruct it fr...

ls shows files and directories in present working directory. (if no arguments are passed.) (It doesn't show hidden files which starts with . by default.) user@ubuntu14:/usr$ ls bin games include lib lib32 local sbin share src To see all files (hidden files/folders also). Use ls -a OR l...

For Adding this to project you can find official doc easily but in this example I'm going to highlight some of the key areas to be taken care of. Step 1 :- Add google service dependencies { ... compile 'com.google.android.gms:play-services-appindexing:9.4.0' ... } Step...
