Hi, I have a list of boxes like
m=. 1; 2 3 5; 4 5
All the boxes contain lists whose items have the same shape. So it is
meaningful to make a combined list, eg convert m to
n=.1, 2 3 5, 4 5
As the individual lists differ in length, using >"0 produces unwanted
padding.
The brute force approach
(>0{m), etc
works. But I am looking for a smart solution.
