But what do you mean by t[[1;;0,1;;1]]?
Could a Span be from 1 to 0?
I've never seen this before.
Can't find an usage/example in Mathematica documents.
This is how I use Span for a matrix:
In[]= t = {{1, 2, 3, 4}, {5, 6, 7, 8}}
Out[]= {{1, 2, 3, 4}, {5, 6, 7, 8}}
In[]= t[[1 ;; 2, 2 ;; 3]] = a
Out[]= a
In[]= t
Out[]= {{1, a, a, 4}, {5, a, a, 8}}
