Hi,

I found something like this with matrix dot

matrix( [a, b], [c, d] ) . invert( matrix( [3] ) )

gave me the 'expected' result

[ a  b ] * 1/3
[ c  d ]

but .. matrix( [a, b], [c, d] ) . matrix( [3] )

didn't give me the expected result of

[ a  b ] * 3
[ c  d ]

instead it gave error message.. incompatible dimensions - cannot multiply

I think it would be better.. if it give the expected result instead of
error message.
What do you think?

Best regards,
bowo
