Not sure why, but this maplet freezes a couple of seconds after picking something from the listbox

with(Maplets[Elements]):

maplet:=Maplet([[ListBox_LB1(FileTools:-ListDirectory("c:/"),'onchange'='A1')]],Action_'A1'(Shutdown(['LB1']))):

I want to use the poset package on Maple 14 but am having trouble installing it. Could someone give me a heads up.

Thanks

Dear friends,

Here a toy version of my problem. I would like  to write several equations and to export all of them to latex. It consist

in three steps

FIRST  I would like to generate for

j1=0..2:

j2=0..2;

j3=0..2;

the equations(for all the combinations of j1, j2 and j3):

assume(a>0, b>0, c>0, d >0, Qs >0):

j1*a + j2*b + j3*c + k/d*X1 = Q1

Basically I just want to have a maplet read a directory and then be able to select a maple file from within the maplet that loads into a new worksheet.

So in a very primitive form

FileTools[ListDirectory]("c:/mymaplefiles")

choose a file and load the file into maple

WORKSHEET_INTERFACE(display,file="c:/mymaplefiles/ the chosen file.mw")

How can this be done in a maplet?

I am unable to solve the following differential equation for u(t). I right-click and select Solve DE but it gives me an incomprehensible solution. Kindly tell me how what to do:

diff(u(t)^2, t, t)+`&x`(`&x`(alpha, u(t)), diff(u(t), t))+`&x`(beta, u(t)^3) = 0

The same equation in "String" notation:

"2*diff(u(t),t)^2+2*u(t)*diff(diff(u(t),t),t)+alpha*u(t)*diff(u(t),t)+beta*u(t)^3 = 0"

The same equation in D notation:

1map.msim

Hello,

I use maplesim to simulate a simple delay system,as the document illustrated,I set the delay values from 0 to 4*Pi/(3*sqrt(3)) . I want to use a single souce to drive four branches, and use "probe" block to generate a figure which contains four curves according to different delays. So I use  a block "4-port Demultiplexer" which selected from Signal Blocks\Routing\Demultiplexers,...

Hi, every body

I have a problem for 4 month ago. This problem is the label in figure. i want to put at label any experssion such as

x*, or x_r or line above x  so on ,

please please please help me

it is a good idea if you provide maple sheet to make it easy understand how use it

Hello,

I have a transcendental equation

equ := 2+(s+1)*exp(tau*s) = 0

where s is a complex variable,and the range of tau is tau = 0 .. 1, I want to plot the trajectory of every roots,namely,s, in a complex plane according to the variety of tau. I try to use the command implicitplot, but get a curve in real plane.

Can you help me?

Best regards.

Hi,

In Classic, you can also first issue plotsetup(maplet) and get a Java-based plotter that supports more 2D Math. That plotter will show nicely typeset subscripts using your original example's syntax plot(y[r]^2,labels=[y[r],x[c]]) .

However, when i want to export as eps it exported it but without color.

could...

Hello (again),

is there a possibility in MAPLE to draw multiple plots on a e.g. 2x2 grid (see image below). In Gnuplot this is feasible with the multiplot option? Is there a MAPLE equivalent...

Hello,

i'd like to fit data of a Matrix M with M[x][y] = z(x,y) to a general parabola of the form: z=a*x^2+b*y^2+c*x+d*y+e

I'd like to use the statistics[Fit] package. Reading the documentation this should work but it doesn't

Please try the following code as example:

with(combinat);
with(Statistics);
M := randmatrix(5, 5);
XYValues := convert(sort(permute([seq(1 .. 5), seq(1 .. 5)], 2)), matrix);
ZValues := convert(Flatten(convert(M, listlist)), vector);

Hello.

I want to find books of probability or stadistics where all topics are explained in depth. I need books where all formulas are deduced and all theorems are demonstrated.

May somedody recommend to me some books?

hey there,

i have a textfile with three columns and i am using the "readdata" command. the first column is a filepath that i read in as a string. unfortunately the filepath is saved with backslashes ("c:\data\...") and therefore i cannot open the file that is indicated by the path. how can i replace the backslashes with forward slashes? any other ideas are also appreciated. thanks!

given 2 pools of letters, i need a procedure to select from the list of 2 letter permutations the appropriate candidates (that are in the correct order).

permute produces a lot of candidates, but i need an english word formed in the correct order.

attached file should explain

thanks
