I’m trying to sample a random matrix, where each element is independent. For example, if I have a matrix of means
M = [1. 10.; 100. 1000.]
and I want to generate data, where each element is sampled as an exponential with mean corresponding to the element of M. The following roughly works
D = map(x -> rand(Exponential(x), 1), M)
This generates an array of arrays though, instead of a 2x2 array (matrix). Any cleaner way to generate a matrix, instead of having to convert the array of arrays to the appropriate shape?
