Iam a Student in the faculty of engineering Petroleum department. Iam Studying Oil Reservoir Simulation which havs many models. Iam Studying the mathematical modeling of those reservoirs. In this modeling we use PDEs to model that reservoir behaviour for years we devide the reservoir into grid blocks each of its special dimensions and parameters so for each grid block there are 3 phases which are oil, water, and gas equation (one for each phase of them)(Matrix Dimension = No. of phases * No. of grid blocks) in addition to the other parameters there are some elements of the PDEs which is function in more than one parameter

Dear All, I am enquiring as to how the "Eigenvectors" function in Maple (I am using version 10) orders the eigenvalues that it returns (and hence the eigenvectors). That is to say, if I input it with a matrix of complex floats, does it just return the eigenvalues it happens to find randomly, or is there some ordering in the vector of eigenvalues it returns? I ask this because if I input it with say a diagonal matrix that is symmetric about it's centre, then the vector of eignevalues returned is also symmetric. Is this just a coincidence in that maple happens to find the eigenvalues in that order, or does it choose to return them in that order? Otherwise, if there is no symmetry in the input matrix then there appears to be no symmetry in the returned vector of eigenvalues.

Steve Forrest and I are building a static analyzer for Maple code. What we would like is some kernel bound self-contained Maple code. In other words, we want code that does not depend on any Library functions, just the Maple language (and itself). Static analysis is already quite difficult, we have to start "small" and build up. Later, we will allow certain library functions -- essentially kernel-bound library functions first (call these 1-functions), then functions that only depend on those (ie 2-functions), and so on, until we can deal with n-functions for n large enough. Right now, kernel-bound code only, please!

I just found this. It's not quite Math or Maple related, but I'm sure most of you will appreciate it.

what about connections between mapleprimes and comp.soft-sys.math.maple ? is it possible to build a "bridge" bewteen them? for instance a "forum" in mapleprimes which will recieve all comp.soft-sys.math.maple posts, or a link to open it into the mapleprimes central frame. we could use the google interface? it will be easier to have only one place to concentrate all informations about maple... comp.soft-sys.math.maple

Since the book entries do not yet have their own tracker (like the forums, blogs, etc), I figured I would give a particular entry I crafted on advanced maple programming a bit of a boost by making a blog entry of it, at least until Will get the tracker back online. I did spend a huge amount of time on that book entry, so I want it to get some visibility!

XKCD continues to post some great comics, often relating to math. Check this one out:

And yes, Maple does get it right

So I thought it would be cool to go buy Vista, not thinking that some of my favorite applications won't work in it. So is there a way to install Maple 10 on Vista Home Premium? If so, any help on that would be greatly appreciated. I don't know if I could go a full day without Maple capabilities. Thanks! Brandon

Occasionally when I do an inline solve, the result is shifted to a new line directly below my input (not centered like a ; solve). Is this a known bug? Is there a way to prevent this from happening? Thanks

Does Maple read .DVI files? if so how do you load them if not is what is a good program to read .DVI format.

Does anyone have anymore infromation on the XMLTools[Tranformation]() package function? The help? files are limited and unchanged since 9.5 ( i suspect earlier ) - does the XSLT use XPath or another method, as the schemas ( given in the help files ) use statements like: ...xpath=".//xppmath|.//xppedit"/... Is this strictly and 'xsd:selector' syntax or can the xpath selection be given in an xsl transformation document? - at the moment the statement: ...value-of select=\"node_name/@*|text()\"... will select the attribute of the node and and: ...value-of select=\"node_name\"...

So you have used Maple as a glorified calculator (Maple 101), then wrote a few 1 liners (Maple 201), and even a few larger procedures (Maple 301), where you were both amazed and horrified by 'op'. But when you get serious about programming in Maple, even for not-so-large procedures, what are the fundamental parts of the system that you should know? Other pages in this book talk about particular features. This one is instead a simple list of those Maple commands and concepts you need to know to be able to call yourself a Master Maple Programmer.

The left hand navigation bar calls it High Performance Maple Programming Techniques but the book itself is (now) called Tools of the Maple Masters.

It took me forever to find which tags were allowed. Why? because, silly me, I searched for it. And there is no page that has that information on it. Or, to be more precise, pretty much every page has that information in it, in the JavaScript region at the bottom of the input box. It is also interesting to note that the tags listed there do not include 'blockquote', and yet the toolbar does.

In my latest blog post, I used both the cite tag and the blockquote tag, to see if they did anything different. They do not. Worse, neither does what they are supposed to do, which is to indent what I post, so that it stands out. Why? Another issue seems to be that, according to the W3C, you can't have raw text in a blockquote, you are suppose to have enclosing tags (like 'p' for example), otherwise what you get isn't valid. So why does the button generate known invalid html? It's one thing for Microsoft to flaunt standards, but...
