![]() We will also try to generate same random numbers in Numpy and Matlab. In what follows, we will try to generate uniform-distributed random numbers in Numpy and Matlab, respectively. n-D array ( n-dimensional array) refers to nth-order tensor.3-D array (three-dimensional array) refers to third-order tensor.2-D array (two-dimensional array) refers to matrix.1-D array (one-dimensional array) refers to vector.In both Numpy and Matlab, they can handle computations of different arrays: We have the following output: sample = 0.7713 0.0208 Comparing Rand Functions in Numpy and Matlab Therefore, random seed is another important concept, which allows one to fix the random numbers in each time.įor example, the following Python code: import numpy as np np.ed(10) sample = np.random.rand(2) print(sample) It is possible to use a certain command/function to generate random numbers following one specific distribution, but every time we reproduce our codes, the generated random number would be different. We can generate random numbers that follow the standard normal distribution: Numpy in Python: import numpy as np sample = np.random.rand(2) print(sample)Ībove examples are about uniform-distributed random numbers. In Matlab, we can use rand to generate uniform-distributed random numbers. ![]() In Numpy, we can use to generate uniform-distributed random numbers. There are two critical concepts:įor random number distributions, we usually take into account uniform distribution and standard normal (Gaussian) distribution. Random Numbers and Arraysīoth Matlab and Numpy can generate random numbers and arrays according to a certain command. In particular, we make a comparison between Matlab and Numpy for reproducing the same random numbers and arrays. In this post, we will discuss how to generate random numbers and arrays in both Matlab and Numpy. However, they are not completely the same. ![]() Ī common feature of Numpy and Matlab is their broad use in matrix computations and numerical computing.
