WebbThis gives for me the same numbers for rand() and np.random.random(), however not for randn, I am not sure if there is an easy method for that. With newer matlab versions you can probably set up a RandStream with the same properties as numpy, for older you can reproduce numpy's randn in matlab (or vice versa). Webb27 okt. 2012 · Matlab randn generates realisations from a normal distribution with zero mean and a standard deviation of 1. Samples from any other normal distribution can simply be generated via: numSamples = 1000; mu = 2; sigma = 4; samples = mu + sigma.*randn (numSamples, 1); You can verify this by plotting the histogram: figure;hist (samples (:));

Webb8 apr. 2024 · Answers (1) rand ALWAYS generates numbers in the interval (0,1). ALWAYS. You cannot change that. However, if you bother to read the docs for rand, they suggest that if you want to generate numbers in a different interval, say (a,b), then you can do something like this: That number will lie in the desired interval.

Webb15 juni 2012 · You are right: rand is indeed generating from U (0,1). The issue of open or closed interval is not practically significant as the probability of generating any number on [0,1] is zero (to include endpoints). The probability density function is defined on the closed interval [0,1]. Not sure what lack of sleep amounted to my previous comment's error.
