--- Comment #1 from Jean-Pierre Ledure <[email protected]> ---
Indeed, the logical/math expressions
  (AppendRow) ∀ i ∈ {0 ≤ i ≤ 2} : b(i, 0) ≡ i
  (AppendColumn) ∀ i ∈ {0 ≤ i ≤ 2} : b(0, i) ≡ i
in the help page are both wrong.

The expressions should be SWAPPED. 
Additionally, the examples should be modified into
  (AppendRow) b = SF_Array.AppendRow(Array(), Array(0, 1, 2))
  (AppendColumn) b = SF_Array.AppendColumn(Array(), Array(0, 1, 2))

Note that the error is also present in the comment lines in the source code.

Now, about the mathematical notations, referring to
https://en.wikipedia.org/wiki/Glossary_of_mathematical_symbols , I do not agree
with the AI:

1. The ⇒ sign means 'implies' which is not applicable here.
2. The equal sign '=' and the identity sign '≡' are formally IMO equally valid.
I prefer the latter to not confuse with a variable assignment.

Thanks for reporting the bug.
