Hi! I'm trying to construct a 3 dimensional array from a number of 1 dimensional arrays. Essentially what i would like to do is
a = [f(i, j) for i in 1:n, j in 1:m] where f(i, j) is a function that returns an array (note, f has to construct the entire array at the same time). The code above creates a 2-dimensional array of arrays, but I would like to get a 3-dimensional array with the arrays returned by f in the first dimension with i and j in the second and third dimension, hope you understand a[:,:,1] = [f(1,1) f(2,1) ... f(n,1)] a[:,:,2] = [f(1,2) f(2,2) ... f(n,2)] . . . a[:,:,m] = [f(1,m) f(2,m) ... f(n,m)] f(i,j) are column arrays above. It can be achieved by first creating the large matrix and then filling it a = zeros(Int64, k, n, m) for i in 1:n, j in 1:m a[:,i,j] = f(i,j) end Is this the only way? I find it sort of ugly when its usually possible to do nice construction using comprehensions in other cases.
