MATLAB® and NumPy have a lot in common, but NumPy was created to work with Python, not to be a MATLAB clone. This guide will help MATLAB users get started with NumPy. In MATLAB,

numpy.random.choice — NumPy v1.24 Manual

Generates a random sample from a given array. If an ndarray, a random sample is generated from its elements. If an int, the random sample is generated from np.arange (a). Output shape.

Parameters: size int or tuple of ints, optional. Output shape. If the given shape is, e.g., (m, n, k), then m * n * k samples are drawn. Default is None, in which case a single value is returned.

Parameters a 1-D array-like or int. If an ndarray, a random sample is generated from its elements. If an int, the random sample is generated as if a were np.arange(a) size int or tuple of ints,

The main difference between the two is that Generator relies on an additional BitGenerator to manage state and generate the random bits, which are then transformed into random values

Notes. Setting user-specified probabilities through p uses a more general but less efficient sampler than the default. The general sampler produces a different sample than the

Given an “index” array (a) of integers and a sequence of n arrays (choices), a and each choice array are first broadcast, as necessary, to arrays of a common shape; calling these Ba and

In NumPy, you can generate random numbers with the numpy.random module. From NumPy version 1.17 onwards, it is recommended to use the Generator instance. However, legacy functions such as

In the random module of NumPy, the .choice() method generates a random sample from a specified 1-D array. It is commonly used in simulations, random sampling, and testing

Sampling random rows from a 2-D array is not possible with this function, but is possible with Generator.choice through its axis keyword. Any of the above can be repeated with an arbitrary
