Sorry about the accidental send…
I meant to say I found it interesting to compare the iPhone/iPad ratio
of times for the Hilbert matrix versus the floating point 500 500 -
Time %. H 100x %.500 500?@$1000
iPhone 686.6 18.2
iPad 444.1 4.58
iMaci7 80.0 0.269
%/1] 686.6 18.2, 444.1 4.58,: 80.0
First impressions - wow!
I ran through the install process on plain old 3g connections - no problems.
The app comes up . I was able to step through the initial demos without
problems. The standard J graphics
look great on the iPhone 4.
Is there anyway to change the size of the default session
touch ? then touch J to get the basic help specific to iOS.
There you will see a list of utitlity verbs.

I have probably made the default font too small as all the initial testers
have mentioned this. My eye sight is not good, but I am a fanatic for
screen real
Thanks Eric,
20 point works fine. I'll try some mini-development on this beta and see
how the work
flow goes.
My wife is probably going to kill you as this is definitely not going to
help with my iPhone addiction.

Hey Eric,
This is really impressive and I can confirm that it is working on a 3GS iPhone
as well.
I wonder if the ? could be included as part of the initial examples before the
controls are enabled. It may not stick, but it would not be hard to scroll up
to find the information again. The
I will change ?J to be ?help and perhaps that will be more clear.

Wow! Is a response I've made several times about this new version of j.
Marvelous that such a powerful application is so compact.
Since I couldn't resist, one of the first expressions I entered on my iPhone 4
(not the faster 4s) was -
6!:2 '%. 500 500 ?@$ 1000'
18.2
Amazing!

That's fast. The 2 minutes I got in 2009 is on the same machine I have now
with Intel Core Duo 2 Ghz CPU.
Does the same benchmark work on the iPhone?
