## numpy.empty() function in Python

numpy.empty() The np.empty() function in NumPy is used for creating an array without initializing its entries. This function is particularly useful when you need an array of a specific shape and datatype, but the initial values are not important and will be overwritten during subsequent operations. It is a way to optimize performance by avoiding […]

## What does numpy.eye() do in Python?

The numpy.eye() function in NumPy is used to create an identity matrix. An identity matrix is a special kind of square matrix where all the elements on the main diagonal are ones, and all other elements are zeros. This kind of matrix plays a crucial role in linear algebra, particularly in matrix operations such as

## How to generate Random Array in NumPy?

In this article, we will focus on the random module of NumPy, which allows us to generate random numbers and perform random operations in a variety of ways. Generating NumPy Array of Random Integers To generate random integers between a specified range, you can use the randint() function. Here’s an example of generating a single

## NumPy Array Attributes

NumPy is a library in Python that provides a high-performance multidimensional array objects, along with that it provides the tools for working with these arrays. An array is a central data structure of the NumPy library, and it is used for representing vectors, matrices, and higher-dimensional datasets. Introduction To begin using NumPy, you first need

## How to Create a NumPy Array with Default Values?

In this article, we will look into some of the specialized NumPy Array creation functions to create a NumPy Array with default values Using numpy.zeros() The np.zeros() function is used to create an array where each element is initialized to 0. This is particularly useful when you need an array of a certain size as

## How to Create a NumPy Array in Python?

NumPy module in Python is a powerful library that is used extensively in data manipulation and scientific computing. In this article, we will look how to create NumPy Arrays and some of its basic attributes. What is NumPy? NumPy, stands for Numerical Python, and it is an open-source library that provides support for large, multi-dimensional

## How to use unique_ptr with Arrays in C++?

In Modern C++, we can create unique_ptr object to manage dynamically allocated arrays. However, the syntax for using std::unique_ptr with arrays is a bit different. In this article, we will look into this in more detail. Syntax to use unique_ptr with Arrays When you want a create a unique_ptr object to manage a dynamically allocated

## How to pass unique_ptr into a Function in C++?

Unique pointers (std::unique_ptr) is a Smart Pointer and was introduced in C++11. It provide exclusive ownership of a dynamically allocated memory. Unlike regular pointers or std::shared_ptr, std::unique_ptr ensures there is only one owner for the allocated memory, making it a safe and efficient way to handle dynamic memory in C++. In this article, we will

## How to Return unique_ptr from a function in C++?

Returning a unique_ptr from a function is a common and recommended practice when you want to transfer ownership of dynamically allocated objects without the risk of memory leaks. Here is how you can return a unique_ptr from a function in C++. Returning a unique_ptr Directly C++ supports Return Value Optimization (RVO) and move semantics, which

## Reset unique_ptr in Modern C++

When working with unique_ptr in C++, it’s essential to know how to renounce the ownership of the managed object and free the associated memory when necessary. The unique_ptr class provides the reset() member function for this purpose. The unique_ptr::reset() Function Calling the reset() method on a unique_ptr will perform two operations: Example of reset() function
