Acer, how's that code working out.  I would also be interested to see it.  Are you still working on it?

For image distortion correction, Matlab seems to have a headstart on the amount of tools available for image manipulation.  It shouldn't be too hard to create an algorithm to work in Maple to do the same thing?  It would be nice to have a similar set of tools in maple.  I read an article on Digital image processing about distortion correction using Matlabs zerocross method in the edge function, and corner detection algorithms.  I don't think it would be hard to implement it in Maple.  The procedure would help nicely with this thread http://www.mapleprimes.com/forum/makeedgesimpleclearsmooth

In the first pamplet, I've managed to decipher most of the missing words, which in the most part I believe are correct.  The second page is much harder since there are less clues around the missing word to connect to any missing words, so I did not even attempt to complete it.  I have a lead on some older info and hopefully will be able to post more sometime later next week.

Here is what I have for the first page:

Maple V is a powerful and efficient interactive software for doing
mathematics on a wide range of computer platforms and systems.
Maple V enables you to perform thousands of different symbolic and
numeric calculations quickly and accurately.
Maple's vast library of functions also provides sophisticated scientific
calculations, programming, and document preparation capabilities
allowing the ability to work with standard mathematical notation.

Maple V - Designed with you Needs in mind

Maple V frees you from tedious mathematical manipulations so you
can solve problems faster and concentrate on the creative aspects of
your work.  It enables scientists, engineers, mathematicians, and other
professionals to solve problems with less effort.
Educators and students, Maple V is
a suitable educational tool for
solving mathematics.

Maple V is used in education, business,
and industry for any application requiring
practical computation - from
engineering design, manufacturing and
product simulation, to statistics, finance
and economics, to quantum physics,
astronomy, chemistry, and more.

Powerful, efficient and accurate
Maple V uses memory efficiently since its library functions (which are
programmed in the Maple language) are loaded only as needed.  This
means that Maple V can solve complex problems with as little as 4 MB
of space. Maple has been refined and updated over many years by
----- scientists and mathematicians, giving you a high degree of
----ational accuracy and efficiency.

Programming Capability
You can use Maple's extensive programming language to tailor the
programs problem-solving power to your specific needs.  Maple V
let's you to examine (and even customize) its own routines.

 

I don't know much about this but it is quite interesting.  Wether Maple becomes an efficient system utilizing multiple CPU processors or putting the GPU's to work, albeit as complicated as that may be, it could be quite a nice piece of software. 

Okay I'll try again.  So again after getting the files unzip part1 first then unzip part2 and you should be able to pull out the pdf file I put together. 

Part1: Download 8990_Lecture complete notes part1.zip
View file details

Part2: Download 8990_Lecture complete notes.zip
View file details

*** edit added *** aha!  figured out why it didn't work.  After downloading remove the 8990_ from the filenames.  They got added when I uploaded the file.  Then it should work properly.

For the benefit to others I've compiled the notes.  They are in two parts because I had to span across two files since the maximum size to upload was 0.8Mb

After getting both files you have to unzip Part 1.  It should have a Z01 extension which was not allowed to upload.  Then unzip from the second file and you will have my complete notes PDF file I compiled. 

** edit deleted the links ** sorry I can't get the zipped files to work in their separated and zipped format. 

On that note how do you delete uploaded files from your files link?

I've compiled the whole course lecture notes for myself into one PDF file and can share them.  I can upload it here but I'm not sure whether I can do that without consent from the author/professor who made them.  I would think I could since each lecture is freely downloadable.  I'm sure there's nothing against that. 

Can anyone advise me on this?  Maybe before I upload, do you think anyone is even interested?

 

**edit - add**  Maximum file size to upload is 0.8 Mb.  And rar file extensions are not allowed - not sure why.  Anyways I'll have to use winzip.

By your only response is to me, Doug, in this thread I am assuming you are referring to me Christopher2222.  Which I hope is not.  Please clarify you are referring to Torontogino.  Otherwise I feel offended by the post.

Torontogino looks like, yes, he is posting homework questions and I had mistakenly while reading had a question while reading his posted under the same thread.

I suppose Maple's biggest hurdle is how to get dedicated MATLAB and Mathematica users to buy Maple and also how to stop Maple users from needing to use, or switch to, competitors software.  Of course having all of them complements each other.  

Maybe Maples Java environment slows it down?  But changing the background Maple runs in would require a complete rewrite of the software, probably not the best option. 

I would like Maple to show, not just what it can do, or improvements that have been made but how it compares itself to MATLAB and Mathematica.  However it could be a risky avenue to approach. 

A more versatile option would be to use range=1..(max(data)+1) this would ensure the last two points are not merged and the data values for 1 are graphed directly beside the y-axis.

binwidth = -1 option should be allowed in case user wants histogram bars to be filled to the left of the number. 

Or instead maplesoft for the future could add a Histogram option like bins=centered, left or right

Strange if I use binwidth - it seems to join the last two points in the data

data := [ 1,2,3,4,5,6,1,2,3,4,5 ]:
with( Statistics ):
Histogram(data,frequencyscale=absolute,binwidth=1);
 

One must use range=0..7.  As Doug mentioned it takes a bit of tweaking as the default is not as one might think.

I would like to see Image tools and audio tools package improved and expanded. 

In the AudioTools package the option to change to Mono to Stereo is really just copying over and filling a second channel with the same sound.  How about including some parameters to change the delay, crossover, offset  etc... in the other channel to make a more realistic stereo sound?  Maybe forcing specific sounds to specific channels ... merging them etc... and increase the number of formats supported.

In the ImageTools package ... I suppose a user defined procedure could be designed to do this but a command to change only specific positions in an image with certain values to another defined value.  Yes I'm sure that could be done. 

Generally some expansions in these areas. 

**edit - added **  The ability to open multiple browse windows for matricies, currently only allowed to one window open.
