- i retested j vs. z language and found the results to be much
- more encouraging.
-
- the following tests were made on the same machine with the j6,
- (i had tested j5 earlier).
-
- j is still some 37% slower, but i think the difference can be
- partially accounted for by the fact that j allows complex numbers
- and z does not, and j allows n-dimensional arrays where z allows
- up to 3 dimensions.
