WebOct 8, 2024 · Syntax : np.multivariate_normal (mean, matrix, size) Return : Return the array of multivariate normal values. Example #1 : In this example we can see that by … WebI'm trying to generate random variables. I read about Box-Muller transform which is a way to generate a pair of normal variables, 2-d normal distrubution. But how do I expand that transform to generate 3-d, 4-d, etc. normal variables with this approach? Or is there a different approach to consider?
