I have a system with the following config:

But when I run my worksheet, only 10% of CPU and 8% of the RAM are working, and it takes one hour my wrksheet to be computed, I am wondering why Maple do not use enough CPU and RAM to do the computation fast.

What is the justification behind this? Is there a way to coerce the Maple to use more capacities of the CPU and RAM to speed up the computations?

In a for loop how is it possible to see online value of the specific parameter during the loop running?

For example I want to see the online value of the parameter t only not j and k, but it seems maple gives out all parameters.

In Matlab it is easily done by ignoring the end ; at the specified pararmeter computation as

How is it possible?

So I'm new to maple, more used to working in matlab. Anyway, I'm trying to solve the pendulum equation with a friction term, but the "dsolve" command spits out something I have no clue how to handle. What do I do with the "theta = _a & where [loads of bullshit]"? It's supposed to give me an integral of some sort that I can work with, not a strange substitution. Halp! 

I got bit by Maple when I tried to combine a number of 2-d plots into one 3-d plot, using plottools:-transform to space the plots out in the third dimentsion. I have done such things before. This time, the first time I executed the final plot statement the GUI got clobbered and somehow also the whole worksheet (I may have saved it). Now, when I load it nothing shows up and worse, I cannot enter anything in the worksheet, it is completely screwy. I looked at the XML code in Emacs and it validates and I cannot find anything obviously wrong with it, i.e. no dangling tags or similar.

I used Maple 2017. In Maple 2015 the same worksheet overprints itself & makes a big mess on the screen. It is similarly unuseable.

Can one of the experts have a look at this? Although rare I have experienced similar issues on occasion before & would like to know how to get this into a sane state.

TIA,

Mac Dude

I simply used solve to solve an equation but it doesn't work properly , Here is my code :

I want to solve system of nonlinear ODEs using RKF with shooting technique. If some body have a idea please help me coding I am new In Maple. If somebody have a relevant code please share with me. I try to understand and then apply on my problem. 

I want to solve attached link paper and image.Thanks

Hi,

I am trying to compute the following integral:

int(a*b*c/sqrt((x-a)^2 + (y-b)^2 + (z-c)^2), [a=-1..1, b=-1..1, c=-1..1])

where x, y, z are Real parameters.

The integral looks so simple but Maple can't compute it as is.

Thanks

Hi

I would like to solve the integrodifferential equation and then look to the  stability of the origin.

Is it  stable, uniformly stable, asymptotically stable and uniformly asumptotically stable.

Please see the following code.

Thanks

We have just released updates to Maple and MapleSim, which provide corrections and improvements to product functionality.

As usual, the Maple update is available through Tools>Check for Updates in Maple, and is also available from our website on the Maple 2018.2.1 download page, where you can also find more details.

For MapleSim users, use Help>Check for Updates or visit the MapleSim 2018.2.1 download page.

I have to use the Chinese Remainder Theorem but once I have found m^e I cant seem to figure out a way that works to get just the message without the exponent. I assumed that the exponent is 3 since the message was encrypted 3 different times. How can I do this with Maple?

Hi all. how can i detect and remove the lists with same members? for example in the code below, i want to remove duplicate of the lists with the same members, for example [1,1,5],[1,5,1],[5,1,1]. i want just one of these sets to remain and the others to be removed. it doesn't matter which. i want just one set with members 1,5,1 which their summation is 7. and the same thing for other lists. thanks in advance.

I know this is a trivial worksheet (in document mode) but why does the second subs fail? Thanks  Gravity.mw

I am having problems when trying to sue de colorscheme opiton. I always get an error message. The example below is from the Maple homepage:

plot3d(sin(x)*cos(y), x = 0 .. 4*Pi, y = 0 .. 4*Pi, view = [default, default, -3 .. 3], colorscheme = ["xgradient", ["Green", "Purple", "Blue"]]);
Error, (in plot3d) unexpected option: colorscheme = ["xgradient", ["Green", "Purple", "Blue"]]

Any hint?

Hi I'm done this and I really have no Idea what's wrong with maple :

I have no idea how to solve the equation ...
Thanks in advance !

Hello, i am trying to solve the PDE

 (E*I) d⁴/dx⁴ [w(x,t)] + (rho*A) d²/dt² [w(x,t)]=0

where w(x,t) = W(x) * cos (ω *t)

W(x) is the amplitude of the beam, the PDE is solved for W(x) by seperation of variables.

my first question is how to simplify the equations by replacing the e^ terms with alpha as done in the lecture, so that things look cleaner. And the next question is how do i proceed to input the Boundary conditions to solve the problem? I have looked in quite a lot of places but there is no example of a second or third order boundary condition(if that makes sense)
