MaplePrimes Questions

Hi,

I have reinstalled Maple 2016 on a new computer, the installation is fine. However, with time, on the old computer, I made several adjustments in the Tools->Options menu, I have added tasks, selected some palettes, removed some others, etc... Is there a way to transport those settings all at once, without performing all that again?

Thanks.

Hello

I wonder if there is a way to see the progress of a specific procedure.  I have checked the forum for some answers and found that some of them propose a progress bar. However the progress bar doesn't seem to fit within a procedure.   

I don't need anything fancy but I need to see the progress of the loop inside of the procedure (over 3,000,000 times).   

Any suggestions?   

Many thanks

 

PS. I am running Maple 2016 too but I would rather see a solution that works on Maple 14 too, if possible.

Is it possible to create several animation windows and run them simultaneously? 

I'm feeling that the answer to this question will be no, so I explain my problem. I have an animation of rotating object and I have some quantity that relates to the rotation. I want to see the rotation of object and the propagation of the graph of the quantity simultaneously. Maybe there is a way to somehow split the plot window in two, so in the left would be the rotation animation, and in the right would be the function animation.

Hi,

I am trying to substitute an general function pde expression I have derived in maple into another general function pde expression but cannot seem to find a method that works. 

Attached is an example worksheet - any help offered would be much appreciated.

Thanks

Hey, I have a problem loading one of my maple files as the headline states.

I have seen a sugestion on how to fix it:

http://www.mapleprimes.com/questions/129377-There-Were-Problems-During-The-Loading

but I do not know how to use it proberly, and can therefore not fix my problem.

What do I do?

I want to generate table of 2 , how can i do this?

Dear Community,

Would someone have a good and easy to understand/implement description of the Den Iseger algorithm for the numerical inversion of Laplace transform? Even better if someone would have a Maple script to do it, that would be superb.

Tx in advance,

best regards

hi...

how i can save results in text file?

for example in attached code maple i want save results for different ''x'' and fy(x), wherer x is between 0 to 1 i.e. (0,fy(0)) , (0.1,fy(0.1)) ,(0.2,fy(0.2)),....

in text file two column should be create.one of them for ''x'' and the onther for ,fy(x)

thanks...

Hello:

I want to make a package or module. Not sure. I cant get my head around what to do. I have loads of formulas I would like to be able to use without going back through work sheets. At present just want to keep it simple.

Have loaded a sample work sheet to use

Intend to place package in Maple2016 library folder.

Very new to using Maple or coding in general. Ran into a problem that I couldn't figure it out.

Any help would be greatly appreciated.

Has anyone been able to do multivariate partial fraction decomposition in maple (here is a paper introducing the idea https://arxiv.org/pdf/1206.4740.pdf)

I often find maple generating complicated rational functions that it would be nice to visualise in other ways

Here is an example of such a function if anyone wants to have a play:

 

(a*x^3+b*x*y^2+a*x*y+b*y^2)

/(a*x^3+a*b*x*y^2+a*b*y*x^2+b*y^3)

 

Hi There:

i have big expressions with many variables of the form (say)  Q__T(t). I would like to simplify my visual parsing of them.

I was wondering if there is a way to tell maple to print particular symbols/variables in specific colors (something akin to what the Physics package does). I.e. I would imagine saying something like:

setup_print_color(Q__T(t), "red");

and then every time Q__T(t) would come up, it would be printed in my desired color.

is this easily possible? I've looked through docs and this site, but can't find any info.

thanks

 

 

Hello guys

 

I am trying to solve a non-linear 2nd order diffential equation in order to describe the turbulence phenomena for tip vortices .

The initial conditions that i have are

b(0)=1

b(8)=exp(.1842068074*ln(-(2.*(-1.+b(x)))/(2.*b(8)-7.))+9.670857391)

Moreover i know that b from 0 to 1 equals one and then it  increases propably parabololoid(from the experimntal measurements)with respect o Re(Reynolds)

I tried to solve the eqution using maple solve de interactivelly but doesnt seem to work

Do you have any suggestions?

Thank you

I attempted to use convolution in AudioTools to convolve 2 vectors with arbitrary values, but could not since the operation is expecting numeric values.  Can this be done?    Is there not a convolution operastor in the LinearAlgebra package?  See attached:
