Re: [Gretl-devel] ** documentation glitch
BTW, it happened to me that I mistakenly used ** for scalar exponentiation, but gretl
treated the whole thing as a matrix expression with Kronecker product. So for 1**0 I got 0
instead of 1! I'm not necessarily saying this is a bug, but a script definitely can be
hard to debug with this. So I'm not sure the automatic scalar-to-matrix conversion is
good here. What do you think?

The *)!"$ web frontend ate my message, I'll try again:
>>From the manual:
12.5 Matrix–scalar operators
...
(Note that the operator ** cannot be used in place of ^ for this purpose
because in a matrix context
it is reserved for the Kronecker product.)
AFAICS it's always ^ in gretl, regardless of the context, no? I don't
remember if that was different before. IMHO it's a bit misleading.
thanks,
sven
