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...

Regards,

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

i need to calculate the radius of an arc. i have that the chord lenght is 96 inches and the distance between the chord and the arc is 6 inches perpendicular from the center of the chord. assuming that i am working with a circle.... how do i calculate the radius of the circle????

Let f:Rⁿ  -> R^m a linear function i need help about a proc about matrix of the linear map Df(x),

our input will be n,m and f

such that,f:R²->R³ ,f(x,y,z)->(x+y,y+2z,x+y+z) and i wish resulting output with derivative matrix with respect to the standard bases in R² and R³

it just won't work

simply hovering over tools crashes it

going into a menu crashes it

trying to execute a command crashes it

it just freezes up completely such that it won't even close down without using task manager

i know fully how to use maple, i've used it on my university network but using it on my home pc won't work for some reason, even though my computer is very modern and i am sure meets the specs.

is this a common thing?...
