## 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?
