Webb11 apr. 2024 · Perhaps you want just a single random number drawn from a Gaussian distribution: Theme randomNumber = desiredStdDev * randn (1) + desiredMeanValue; y (j) = x (j) + Sig2 * randomNumber; Be sure to assign the desired mean and standard deviation to some values that make sense for your other values. Webb26 aug. 2024 · I am minimizing distance between points in a matrix to random vectors in a matrix, while producing a K-means algorithm.
