Dear guys! It seems to me that we can not use "subs" after solving an ODE system by method=classical[rk4]. Am I right? If your answer is yes then how should Ido instead? 

Hi all! Can any body tell me what " relerr " does in maple. I have seen it in a .mw file but I don't find it in maple help, why? 

Hello! I have an ideal in 12 variables. I wish to eliminate the last four. I did:

ord := lexdeg([x[9],x[10],x[11],x[12]], [x[1],...,x[8]]);

gb_myI := Basis(myI, ord);

However, the resulting Grobner basis had all 12 variables. Did I misapply the lexdeg? Or perhaps I don't quite understand the eliminnation order?

Any help or comments would be appreciated!

Best,

Susan

I have tried to solve a certain problem but I can't go on since

Maple can't do rational functions computation.

I wanted to solve Wx1v for funcF1 but Maple couldn't. 

So I solved it manually. If I substitute F1 into Wx1v,

Maple should give 0. But it doesn't. Maple couldn't simplify

computations. Any help? Thanks!

Hi

Is there a way to change the font size when doing an "export as pdf" from the file menu? It it currently much to big for me (both in plots as well as other text). I use worksheets (not documents) exclusively.

thanks

tryed to compile samples\OpenMaple\cmaple\omexample.c in MS Visual C++ Express 2010. Everything is OK but after running is writes "The program can't start because maplec.dll is missing from your computer..." Why? I've linked maplec.lib statically! Besides \Maple\bin.win\ in my library path where both maplec.dll and maplec.lib are. System - Win7 Home Premium +SP1

Why doesn't HTTP[Get] work with the question mark?

for example

a := HTTP[Get]("www.mapleprimes.com/recent/all")  # works to get the first page

a := HTTP[Get]("www.mapleprimes.com/recent/all?page=2")  #  Shows file directory not found

How do I get it working so

Hi simulators

Is there an easy way to give a global time frame/limits for all plots: typically I need to simulate a few seconds to get rid of all my transients, and then I would like to zoom in on the effect of interest. Now I have only found out how to reset one by one each graph via the axis properties, I have a dozen graphs per simulation 4 variables to scan over ten points each, that makes a damn lot of graphs properties click to reset, results: I need 60 sec to...

Hi

I need a procedure to multiply a fractional number by an integer (n), to produce (the closest) integer (m).

eg 1.333333 * 3 = 3.99999 (4)

i/p fractional number

o/p: n=3, m=4

Let a partition of a planar polygon into colored polygons be given, i.e. something similar to

  We know the coordinates of the vertices and the color of each part, e. g. in such a way:
>with(plottools): with(plots):
>display(polygon([[.12, 1.28], [3.07, 4.54], [3.41, 1.69]]), color = red, thickness = 2, view = [-1 .. 5, -1 .. 5]);

Student here. I'm having a real hard time with Maple's help. Can someone tell me how to create F, without having to type the whole thing in (like I just did) each time I change N. F is really just columns of omega raised to the (column-1)*(row-1) power

I also need help with the syntax for pulling out a column of F, and multiplying A (an NxN matrix) by that column,

A*F(column n):

I am looking for an implementation of the Mathematica equivalent of RegionPlot whose description should be like:

RegionPlot(pred,x=x_min..x_max, y=y_min..y_max) makes a plot showing the region in which pred is True.

For example, I would like to execute:

> RegionPlot(f(x,y) > 0 and g(x,y), x=x_min..x_max, y=y_min..y_max)

where g(x,y) outputs True/False.

One idea I had was to use:

> densityplot(`if`(pred,1,0...

Hello

I wanted to vary my mass item in MapleSim5, to have it appear and dissapear. I noted I could us the variable "1*t" [kg] in a rigid body mass item, that worked out fine

Then I wanted to have a force variable depending on the time, but now I get a message Main.t is not defined in Main

So finally how to refer correctly to the "time" ?

Subdiary question: how to use signal blocks to generate a named variable that I use elswhere in my model for a Parameter input

Dear guys! I'm solving a system of ODEs in a for loop with different initial conditions and after that in each loop I use the result to solve an integral and after all I find the minimum value of integrals. But the problem is that when I write for loop with for example 100 initial conditions I get a result and when I expand the numbers to for example 1000 initial conditions where include the 100 previous one maple tell me that the initial conditions that make the integrel minimum are the same ...
