Importing numpy: We first import the numpy library for array manipulations. Initializing arrays: Two arrays are initialized, one 2D array of shape (3, 5) and one 1D array of shape (3,). Transposing the 2D array: The 2D array is transposed to get a new shape of (5, 3). Broadcasting...
Python. It is used for different types of scientific operations in python. Numpy is a vast library in python which is used for almost every kind of scientific or mathematical operation. It is itself an array which is a collection of various methods and functions for processing the arrays. ...
Importing numpy: We first import the numpy library for array manipulations. Initializing arrays: Two 1D arrays of shape (5,) are initialized. Reshaping arrays: The arrays are reshaped to (5, 1) and (1, 5) respectively to enable broadcasting. Broadcasting and Addition: Element-wise...

Quaternion components are stored as double-precision floating point numbers — floats, in python language, or float64 in more precise numpy language. Numpy arrays with dtype=quaternion can be accessed as arrays of doubles without any (slow, memory-consuming) copying of data; rather, a view of ...
