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 ...

Linux Requirements (r0.16.0) Mandatory As per current Apache-Pig documentation it supports only Unix & Windows operating systems. Hadoop 0.23.X, 1.X or 2.X Java 1.6 or Later versions installed and JAVA_HOME environment variable set to Java installation directory Optional Python 2.7 ...

import scala.concurrent.Future import scala.concurrent.ExecutionContext.Implicits.global object FutureDivider { def divide(a: Int, b: Int): Future[Int] = Future { // Note that this is integer division. a / b } } Quite simply, the divide method creates a Future tha...

A very interesting type of JOIN is the LATERAL JOIN (new in PostgreSQL 9.3+), which is also known as CROSS APPLY/OUTER APPLY in SQL-Server & Oracle. The basic idea is that a table-valued function (or inline subquery) gets applied for every row you join. This makes it possible to, for example...

If you implement a text-search as LIKE-query, you usually do it like this: SELECT * FROM T_Whatever WHERE SomeField LIKE CONCAT('%', @in_SearchText, '%') However, (apart from the fact that you shouldn't necessarely use LIKE when you can use fulltext-search) this creates a problem when someb...

To read default configuration properties: package com.example; public class ExampleApplication { private Properties getDefaults() throws IOException { Properties defaults = new Properties(); try (InputStream defaultsStream = ExampleApplication.class.getResou...

SOAP services can publish metadata that describes the methods that may be invoked by clients. Clients can use tools such as Visual Studio to automatically generate code (known as client proxies). The proxies hide the complexity of invoking a service. To invoke a service, one merely invokes a metho...

View components encapsulate reusable pieces of logic and views. They are defined by: A ViewComponent class containing the logic for fetching and preparing the data for the view and deciding which view to render. One or more views Since they contain logic, they are more flexible than partial v...

Move a rectangle 10 units to the right and 20 units down: <svg xmlns="http://www.w3.org/2000/svg"> <rect x="0" y="0" width="30" height="30" transform="translate(10, 20)" /> </svg> Move it 0 units horizontally and...

Rotate a polygon clockwise by 90 degrees around the origin: <svg xmlns="http://www.w3.org/2000/svg"> <polygon points="0,0 30,0 15,20" transform="rotate(90)" /> </svg> The result is equivalent to <svg xmlns="http://www.w3.org/2000/svg...

Apply a transformation matrix to a polygon: <svg xmlns="http://www.w3.org/2000/svg"> <polygon points="0,0 30,0 30,30 0,30" transform="matrix(1,0.6,-1.2,1,40,10)" /> </svg> Every point (x,y) will be transformed by applying matrix(a, b, c, d, e...

Transformations can be concatenated and are applied right to left Rotate a rectangle by 90 degrees and then move it down by 20 units and to the right by 20 units: <svg xmlns="http://www.w3.org/2000/svg"> <rect x="-10" y="-20" width="20" height=...

Most of the time printing should be avoided as it can be a distraction (Out should be preferred). That is: a # Out: 1 is always better than print(a) # prints: 1 Prefer supporting python 2 and 3: print(x) # yes! (works same in python 2 and 3) print x # no! (python 2 only) print(x...
