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...

Please i need it urgently.

Thanks.

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 ...

Dear guys! I'd like to know that for solving an integral by maple we have to use " int " or we have any other choices? Because I have an integral with large limits from 0 to for example 1000 and it takes much time for maple to solve it.

Using the tree structure example from ?GraphTheory[DrawGraph] using showlabels=true the highlighted areas are merged and no amount of zooming can seperate the merged yellow areas.

Another issue, I don't see the advantage of style=tree when a tree structure can only be printed if the original DrawGraph is already represented as a tree style structure when...

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 all,

I have two plots, one done in Maple and an other in Matlab. And I want to compare the two plots with superposing the two plots in one plot (in Matlab or in Maple).

Copy from a plot in Maple and past into a plot in Matlab don't work.

What is the easy way to do that ?

Thanks in advance

I have solved my one chapter of my mathematics text book in maple. i want to get is published, but dont know how to format and how to make the page for book publishing, can any one help?

I'm new to Maple, can anyone advise on the best way to create Quiver plots?

Help!

I've used Eigenvectors to solve for eigenvalues & eigenvectors.  Eigenvalues works, no problem.

The eigenvectors are not normalized to unit magnitude (how would I do that for all eigenvectors?) and the usual matrix multiplication of the eigenmatrix by its transpose should give the identity matrix--and somehow it does not. 

Can someone point out the flaw in my thinking?  The file is attached.

Thanks for you insight!
