Consider the following example: public class Example { public int a, b, c, d; public void doIt() { a = b + 1; c = d + 1; } } If this class is used is a single-threaded application, then the observable behavior will be exactly as you would expect. For instan...

Here is a basic class documentation example: /// Class description class Student { // Member description var name: String /// Method description /// /// - parameter content: parameter description /// /// - returns: return value description func say...

Define the variables within a formula field: Shared NumberVar x := 1000; Shared NumberVar y; Assigning the values is optional. To display the variable in a second formula later on in the report, the call is nearly identical: Shared NumberVar x; x

In many application it is necessary to compute the function of two or more arguments. Traditionally, we use for-loops. For example, if we need to calculate the f = exp(-x^2-y^2) (do not use this if you need fast simulations): % code1 x = -1.2:0.2:1.4; y = -2:0.25:3; for nx=1:lenght(x) for n...

Many real-world database tables have many rows with DATETIME OR TIMESTAMP column values spanning a lot of time, including years or even decades. Often it's necessary to use a WHERE clause to retrieve some subset of that timespan. For example, we might want to retrieve rows for the date 1-September-2...

All programming languages allow us to assign values to variables. Usually, a value is assigned to variable, standing on left side. The prototype of the overall assignment operations in any contemporary programming language looks like this: left_operand assignment_operand right_operand instructions_...

Though Go supports ++ and -- operators and the behaviour is found to be almost similar to c/c++, variables with such operators cannot be passed as argument to function. package main import ( "fmt" ) func abcd(a int, b int) { fmt.Println(a," &...

You can attach an image in a texture to a framebuffer, so that you can render directly to that texture. glGenFramebuffers (1, &framebuffer); glBindFramebuffer (GL_FRAMEBUFFER, framebuffer); glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, ...

To set up a default SceneKit project you can use the Game Template.

The Same Database reference allows you to split a single database into multiple projects. This is useful for cases where a project is very large or where different teams manage different parts of the database. If you consider that you have two .sqlproj SSDT database projects with the following stru...

(************************************************* * All comments in SML are block comments * Block Comments begin with '(*' * Block Comments end with '*)' * (* Block Comments can be nested *) * The additional framing asterisks at the beginning * and end of this block comment are common ...

(* The block comment syntax allows nested comments (* whether or not this is a good thing is probably a matter of personal opinion (*or coding standards*)*)*) val _ = print "Nested comment example\n" (* line ending block comment *)

Let's create middleware that adds a property called requestTime to the request object. var requestTime = function (req, res, next) { req.requestTime = Date.now(); next(); }; Now let's modify the logging function from the previous example to utilize the requestTime middleware. myLogge...

Implement onMessageReceived that will catch the notification sent from GCM server. @Override public void onMessageReceived(String from, Bundle data) { String message = data.getString("message"); Log.d(TAG, "From: " + from); Log.d(TAG, "Message: "...

To receive the notification, implement application:didReceiveRemoteNotification:fetchCompletionHandler: (or application:didReceiveRemoteNotification: for iOS < 8.0), and call GCMService:appDidReceiveMessage:message to acknowledge the reception of the message to GCM. - (void)application:(UIApplic...

We initialize the data: [X,Y] = meshgrid(1:2:10); Z = X.*cos(Y) - Y.*sin(X); The surface looks like the following. Now we set the points where we want to interpolate: [Vx,Vy] = meshgrid(1:0.25:10); We now can perform nearest interpolation, Vz = interp2(X,Y,Z,Vx,Vy,'nearest'); line...

We will use the following data: x = 1:5:50; y = randi([-10 10],1,10); Hereby x and y are the coordinates of the data points and z are the points we need information about. z = 0:0.25:50; One way to find the y-values of z is piecewise linear interpolation. z_y = interp1(x,y,z,'linear'); ...

Cannot add Integer and Real* - 5 + 1.0; stdIn:1.2-10.4 Error: operator and operand don't agree [overload conflict] operator domain: [+ ty] * [+ ty] operand: [+ ty] * real in expression: 5 + 1.0

You shouldn't throw raw values as exceptions, instead use one of the standard exception classes or make your own. Having your own exception class inherited from std::exception is a good way to go about it. Here's a custom exception class which directly inherits from std::exception: #include <ex...

The pandas.DataFrame.apply() method is used to apply a given function to an entire DataFrame --- for example, computing the square root of every entry of a given DataFrame or summing across each row of a DataFrame to return a Series. The below is a basic example of usage of this function: # create...
