Hello, is it possible to use Multik cat on an "empty" multik array?
In Numpy we can do the following : https://stackoverflow.com/questions/22732589/concatenating-empty-array-in-numpy

Currently I have the following :
Peusdo code:

val a = mutableListOf<List<Int>>()

for loop
   multikArray = function()
   a.add(multikArray.toList())

val b = mk.ndarray(a)

But It would be nice if I could do :

val a = mk.ndarray(mk[])

for loop
   multikArray = function()
   a.cat(multikArray)

Ok turns out I found a way to do it.

The arrays themselves in multik are immutable. There are several operations that return “view”, but for any operation where consistency is important, the array will be copied
