it just occurred to me (why not before?) that the error message
"matrices not conformable for operation" could be made more useful by
immediately including the dimensions of the matrices involved.
? matrix test1 = zeros(2,2)
? matrix test2 = ones(3,3)
? matrix test3 = test1 * test2
Matrizen nicht passend bei Operation
It wouldn't be too difficult for gretl to amend this message with "2 x 2
and 3 x 3", right?
I think this would be very convenient for script writers, because
currently we have to write some debugging printf statements in the right
places, re-run the script to get the same information, and later delete
