Hello Maple wizards,

I have two questions for you today.

First, a program I'm developing in Maple 15 does frequent matrix multiplication with a constant float[8] matrix. I hope to take advantage of multiple processors in my 6-way desktop processor and/or CUDA features of the Nvidia GPU card. The program is large enough that maintainability and good programming practice dictate that it be broken down into multiple procs. In addition, I'm considering...

I'm thinking about getting a new laptop (since the current one is kind of outdated). I use a lot of Matlab, Maple and Mathematica and will be doing come cfd computations. I found two laptops which, for the same price, only differ in processor and screen size. One features a i7-2620M and has a 13' screen and the other a i7-2670QM with a 15' screen. What I need to know is if the difference between processors is significant enough for me to turn a blind eye on portability ...

When using the command "for", the results are placed in a column,such as if we input
for i from 1 to 3 do  i end do, the results are showed as

1

2

3.

This style is not convient to use for following computation. So how to put all results into a list or set ?

I would like to solve x1v for funcF1(funcr(x),x)). I did similar computations before. 

I think Maple can deal with rational functions very well. It's having a trouble to

use the common denominator the simplify x1v. 

> denom(Wx1v);
                    2           2                            2
               -barv  + funca(x)  D(funcP)(funcr(x)) funcr(x) ...

Hi,

I'm currently using a gridded search to find a global minimum.  I have 4 parameters which results in a really large search size (100 steps per parameter).  In order to reduce my computation time, I'd like to use a gradient search instead.  Does anyone have any code?

Thanks

1.For win 8, does there exist an arm version maple in future?

2.Will it possible to use gpu acceleration for symbolic computation in maple?

Hello,

I want to use the values of the solutions of

sol := solve({x+y=a, x-y=b}, {x,y});

I would like to be able to continue some symbolic computationg, for example

dernier:= sol[1]/sol[2];

but I get an error message.

How can I take only the values of x (and not the expression x= something) to compute, for example "dernier"?

Thanks in advance,

Hey guys, 

Its my first post, so please be lenient. I have done an internship at a theoretical physics department and part of my work was to plot a particular only numerically solvable integral over time (problem from Quantum Mechanics). I wrote a maple code and made it work, but it only produces results for certain values and even for those it takes more than one hour to plot one graph. Since this is my first big project written in maple, i assume, that the code...

This is not a question about any technical problem with Maple.I'm not even sure that is it a question or a post.Since I'm asking something inside it,I consider it as a question.I'm sorroy that it is too long.

In scientific computing(computational physics/chemestry/biology/enginnering),which needs a large amount of data to manipulate and then simulate,some high level programming languages(HLL) are used.

Different fields have different language of choice...

Hello wizards,

I'm given to understand that using add() or if possible Task:-Add() is more efficient than a FOR...DO loop. Today I'm asking about the limits of this generalization. My illustration is probably missing some evalf's, but hopefully the concept is clear:

A computation I'm working on involves between 10E4 and 10E6 computations like

The MRB constant is defined at http://mathworld.wolfram.com/MRBConstant.html.

In September of 1999, I,Marvin Ray Burns, computed the first 5,000 digits of the MRB Constant on a Pentium II IBM Aptiva 350 (CPU type 66MHz Intel i486DX2) Computer with 64 MB of ram.  

I'm using Maple 14 on 4-way and 6-way AMD 64 hardware running Windows Vista to numerically estimate inverses of a cumulative distribution function at hundreds of points, and am using the Task model to assign each point's inverse computation to a separate task. The cdf is a weighted sum of thousands of simpler functions, and so each task needs the weights. Initially I had set these up as a global variable, but after reading Darin Ohashi's MaplePrime's post ...

The term “from months to days” is a favorite slogan of mine and I have relied on it religiously for over two decades to illustrate the fundamental benefit of symbolic computation. Whether it’s the efficient development of complex physical models using MapleSim, or exploration of parametric design surface equations (my dissertation) using good old fashioned Maple V Release 2, the punch that symbolic computation provided was to automate the algebraic mechanics...

I was trying to evaluate a difficult integral on maple analiticaly but after about 5 minutes its output is the integral itself. Something like a=a; is it timing out? How can I change this to let it run for a longer period of time? Also I doubt that there is an analytic solution, so I tried to do a numerical computation, with the assumption that (a>0), and it gave the following output:

Also the original expression that Im trying to integrate...

A lot of people want to do very large computations which require a lot of RAM.  But above a certain threshold, the cost of memory explodes.  We had this idea but no excuse to try it.  Buy a good SSD and use it for a swap partition.  I suggest the Intel X25-M.  Make sure you have at least 1/10th of its size in RAM, i.e. 8GB of RAM for an 80GB drive, but of course more is better.  The RAM should act as a massive cache for the SSD, giving you another...
