In this article, we will write a go language program to find the transpose of a matrix. A matrix is a collection of numbers that are arranged in rows and columns, which is a two-dimensional array. Find The Transpose Of A Matrix The following code illustrates an example to find the transpose of a matrix. Algorithm Step 1 − Import the fmt package. Step 2 − Call the main() function. Step 3 − Initialize a 2-d array called matrixA and matrix and store elements in it. Step 4 − Print the matrices on the screen. Step ... Read More
We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight-line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to implement object duplication programmatically we need to implement duplicate control using the clone method Syntax clone( callback: Object, propertiesToInclude: Array) Parameters Callback (optional) − This parameter is a callback function which is invoked with a clone. propertiesToInclude (optional) − This parameter ...

In this tutorial, we will write an article to find the normal and trace of a matrix. A matrix is considered normal if its square root equals the sum of the squares of each member and the trace is the total of a matrix's diagonal elements. Golang Program To Find The Normal Finding Normal of 2x2 Matrix In this example, we will see how we can find the normal of a 2 X 2 matrix. Algorithm Step 1 − First, we need to import the fmt and math package. Step 2 − Create a function to find the Normal ... Read More
We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to implement delete operation only for a selected object, we need to use the remove method. Syntax remove( ...Object): Self Parameters Object − This property accepts a fabric.Object value which is the object that we want to remove. Example 1: ... Read More
In this tutorial, we will see to write a go language program to find common elements in two arrays. Find Common Array Elements Using User-Defined Function The following code illustrates how we can find the common elements in two different arrays of strings. Algorithm Step 1 − import the fmt package. Step 2 − Define a function named intersection() that accepts the two arrays as arguments and returns the resultant array as an output to the function. Step 3 − Create an empty array of strings called out and a map called bucket. Step 4 − Use for ... Read More
In this tutorial, we will see to write a go language program to copy all the elements of one array to another array. Copy All The Elements Of One Array To Another Array Using Equality Operator Let us now look at a go language code to copy all the elements of one array to another array by using equality operator. Algorithm Step 1 − Impot the fmt package that. Step 2 − Call the main() function. Step 3 − Initialize and define an array of type strings and store values to it. Step 4 − Print this ... Read More
We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. Syntax set(key: String, value: String | Boolean | Number | Object | Function) Parameters key − This parameter accepts an String which specifies the property we want to set. value − This parameter accepts the value to be set for the property. ...

We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to identify if the given object is of a Polygon instance, we use the isType method. This method checks if the object is of the specified type and returns a true or false value depending on that. Syntax isType(type: String): Boolean Parameters ... Read More
In this article, you will learn about logging methods in the Swift language. You will also learn what the differences between them are. Debugging is the most common practice while writing code for an iOS application. It enables you to debug logic, code, errors, etc. Swift provides in-built libraries to print logs on the console. We have some options to print logs on the console like print(), println(), and NSLog(). Let's try to understand each of them. print() In Swift, print() is a function that prints a message to standard output (e.g., the console). It takes one or more arguments, ... Read More
This error is very frequent as you can see many times while writing code. Don't worry, you will understand this error in detail in this article. Before jumping to the cause of this error, let's understand what is optional in Swift. Optional Initially, when we receive a value from another source, such as the backend server, it might contain a valid value or nothing at all. In that case, you use optionals that represent a variable with two possible situations: either a value or no value at all. var possibleNumber = "450" var convertedNumber = Int(possibleNumber) In the above ...
