Is there any easy way to download (or upload) several files in my maplecloud simultaneously. I seem to be able to highlight several files, but when I control-click it then only selects one.

Thanks,

I am trying to solve the so called Bethe ansatz equations in Mathematical Physics.

I have four multivariate polynomials equations with four unknown p_i(x[1],x[2],x[3],x[4]) i=1,2,3,4; which have integer coefficients. The equations are mixed; P_i is linear in x[j] for x[j]\ne x[i]; and x[i] is of order 10. Due to this structure,  I first eliminate x[4] from these equations. Then use resultant to eliminate x[3],  I got error messages (invalid series, in gcd...

Hi,

I'd like to draw a disk with center (0,0,0) , radius 1, in the plane theta=constant (or y=tan(theta) x), where theta is given different of 0.

How can I proceed?

Thanks.

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...

Is there a bug in the CodeTools:-EncodeName / DecodeName pair?

Consider the following minimal example:

with(CodeTools):
M := module() option package; export f; f := proc() end proc; end module;
EncodeName(M:-f);
DecodeName(%);

The EncodeName gives answer:

_Inert_ASSIGNEDLOCALNAME("f", "PROC", 0, _Inert_ATTRIBUTE(_Inert_NAME("protected", _Inert_ATTRIBUTE(_Inert_NAME("protected")))))

But applying...

I am currently taking a course in quantum mechanics using the second edition of McQuarrie's Quantum Chemistry text. I plan to take a QM II course, more concentrating on atomic and molecular spectra. I have been using Mathcad 15, which includes Maple functionality (please pardon my stating the obvious). Mathcad, however, seems to lack functionality (or I have not found it) that would be helpful, like the ability to easily define an operator. Since...

Today, after hours of hunting a persistent bug in a worksheet, I discovered something i did not know about Maples evaluation strategy. Consider the following Maple code:

restart:
a:=1:
b:=a:
b:=2:
a;

Now the variable 'a' holds the value of 1. Now consider the case where 'a' is a vector:

restart;
a:=<1,1>:

However, this does not work.

My problem is not to plot U as a function of time, but somehow convert the function.

I mean, in Your solution U is defined through X(t) and thus Maple is evaluating the solution for DE every time the U is called.

However I would like to have U as function of t without precense of X(t). Since X(t) is a known procedure, there might be the way to explicitly define U as a function of t only, after the evlauation of procedure X(t).

Hi all,

A while ago, I had asked a question relating to calling to an MapleSim .msim simulation within maple .mw worksheet. (Thank you Acer! :) I got it working but then another issue just popped up...The basic structure is as follows:

********************************************************************

A := MapleSim:-LinkModel('filename' = "TriplePendulum_WORKS_v2.msim")

for z from 1 to 50 do

     initialize_variables;

Hi,

how can i install the DirectSearch optimization package for mac version (MAPLE 15)?

HI experts,

can anyone here help mi in transform a Mathematica v8.0 sheet into maple v.15 ?

I am still maple novice.

Thanks a lot

Hey everyone.

I have been trying to solve an ODE with BC with dsolve,numeric but always get the error below:

> Error, (in dsolve/numeric/BVPSolve) matrix is singular

My problem is not solving it (ie fine to do with LinearAlgebra package or similar), but why does this error occur? What is the problem with the ODE/BC that produces this error?

And is there a way of adjusting the ODE/BC to be able to solve it simply by using dsolve,numeric?

I've made exam questions for students that they have to answer by doing some calculations in Maple.

I would like to let them copy the commands they used to a Maple TA text field.

However, the standard worksheet in our computer lab uses 2-D math. Copying this 2-D math to Maple TA works fine with "paste as plain text", but copying 1-D math also works with ctrl-v in Maple TA, which is more convenient for students under stress.

Since I am not allowed change...

Hi there

I'm a new user of Maple 15 and would really appreciate some tips on how to get started, this time more specifically on how to change the axis orientation. I'm a geotechnical engineer and in practice we always plot all the soil properties (strength, density, water content, etc) with depth, and so it should be positive downwards. 

I've seen a few posts where the issue was raised by some people years ago but was just curious to know if the new version...

HI,

 

I want to create a Textbox which will be opened in the beginning of a Maple code. In this Textbox I want to write an integer, which will be used for a following calculation.

I already found this code:

 

> restart; with(Maplets[Elements]);
print(`output redirected...`); # input placeholder
> maplet := Maplet([["Insert Text", BoxCell(TextBox['IB1'](1 .. 10))], [Button("OK", Shutdown(['IB1'])), Button("Cancel", Shutdown())]]);
