Subject: Utils link uppercase instead of lower case

Dear Ken,

I went back to your site and found the utils web page, but the link to
the utils worksheet is mispelled: the file name starts util... but the
link is to Util...  I did a directory listing and found the file.

You might want to fix that.

However, when I tried to execute the utils worksheet, it would not
execute and I had to step by step enter each of the commands. but then I
could succeed in creating a utils.m file anywhere, no matter how I use
the lib commands of you other instructions about MyLib.

I am using MAPLE V5.1.

SO I did not give up. Since the worksheets I downloaded were behaving
funny, I copied the inputs individually into a blank worksheet and added
the MyLib commands after restart (did not work again for savelib), but
added a save to my top level C: location which did work when I executed
the worksheet and then I copied the utils.m and chaos.m files over to my
directory with the other files... Then I found that your chaos help
worksheet does not load utils.m so I added that and finally the help
page started working.

Until the line:
AnimatedGraphicalAnalysis(f,-2,2,.65,50);
which would not execute and each time I tried to enter it, it put a new
blank line underneath and each time I would hit enter, more blank lines,
indicating funny behavior of the worksheet.
[Later note: miraculously, when i deleted the argument 50 
 and retyped it in, it worked!]

Then this happened again with the line:
Bifurcation(Q,-2,0.25,500,100,0);

Then it did not understand "affine" command in the output of:
mb:=BarnsInt([[1,2],[2,3],[3,1],[4,2]],[.4,.4,.4]);

In fact none of the affine commands later on are actually evaluated in
the outputs. Does this mean they have not been defined, or are they
supposed to not be evaluated?

I got nearly to the end of the help file but started running out of
memory so I stopped at 3.5 MEG output file.

It is very nice. I had a book in Mathematica on chaos years ago, hoping
someone would develop this stuff for MAPLE. It looks like you put in  a
lot of work. I hope it has been appreciated.

Anyway, do you have any idea why am I having such difficulties? I would
appreciate any help you can give me.

thanks
bob

Dear Bob,

You are right!  This is just a bug on my part.  I revised the chaos library
(Version 2.53 :) ) and just uploaded it to the web now.  It no longer
requires
the utils library.  The only command in the utils library that I wanted to
have
available in the chaos library is "Table", so what I did is copy the source
code for Table from the utils library to the chaos library.  It should work
as
a standalone library now.  Thanks for pointing out that mistake!

> You output looks very nice.

Thanks.  I would of course be interested in hearing about your experiences
with
the software and am open to suggestions and feedback.  I am teaching the
undergraduate chaos and fractals course this semester, so my students will
be
using that software quite a bit.  I also have lots of other routines I want
to
add to it, so it should be updated quite often during the term.

Thanks for finding that bug!  It's tough to keep all this software straight!

Regards,
KEN
