It's possible for a user to set many defaults within a Maple session. One feature I do not see how to customize is the "point probe" tool. In earlier versions of Maple there was only one mode, and the coordinates of the cursor within a 2D plot were displayed in the context bar of the Maple window.

Now, there are several different modes for viewing coordinates within a plot. By default, the point probe shows nothing about the current location of the cursor. To change the point probe for one plot, right click and select Probe Info from the context menu, then choose one of "Cursor position", "Nearest datum", or "Nearest point on the line".

This has to be repeated for each plot.

Is there a way to set the default?

This works only when the plot "Manipulator" is set to "Point Probe". If it's set to Pan or Scale, this needs to be changed via the icons on the plot toolbar or through the Manipulator entry on the context menu.

Along the same lines, is there a way to set the default Manipulator to Pan or Scale?

If not, these would be nice features to have added for Maple 15.

sendtomap1.mw, sendtomap2.mw, wood_riess.zipHi! I've written a program for my work to obtain "chi square" for a range of data. Can someone tell me why my first example which I have attached and I've called it "sendtomap1" works correctly, but the second one "sendtomap2" has an error?...

Hello!

I'm writting a simple program to obtain chi-squared for my model. I've written it for a costant value of "n" and it correctly works and results chi-squared, but when I want to write a loop for "n" then the program doesn't work at all.

I don't recieve any error message. can you help me?

 

 

I am trying to create a certain visual effect in a Maple document / worksheet.

Basically, I have a small table with colored cells that I want to embed in a worksheet with an altogether different fill color. This sounds simple enough, but it appears that Maple's tables don't allow this.

I built the shock model in MapleSim

then I got the response accleration

For this curve, I want to solve its fourier series in Maple.

Do it work?

this is the msim file

Hi

I'm exporting arrays of plots as html (so I get multiple gif files). At the moment I do this off the menus (file\export as) is there a way to write this command at the prompt in worksheet mode?

thanks

  1. How do I 
  2. Write a maple program to calculate the probability that k cards in 3-dimensonal set game (out of 27 cards) contain a set for k=3…9.

      3  randomly generate 12 cards in 4-dimensonal set game, either find a set or report “no set”.

Can I solve the following two coupled differential equations instead of the previous one in Maple 13?

 with plots

Eq[1]:=3*f(eta)*(diff(f(eta), `$`(eta, 2)))-2*(diff(f(eta), eta))^2+3*g(eta)

Eq[2]:=(diff(g(eta), `$`(eta, 2)))/Pr+f(eta)*(diff(g(eta), eta))

BCs := [f(0), (D(f))(0), g(0)-1, g(25)]

pars := {Pr = 1}

for i to 2 do eq[i] := subs(pars, Eq[i]) end do

eqs := eq[1], eq[2]

vars := f(eta), g(eta)

No that way I could have chosen infinity at 10 or lower values also. f ' will go from 0 to 0 through positive values only. But how can I claim then that my solution is infinity independent. Because if I change the value of infinity whole solution changes.

 

Moreover at 15.6 the value of f ' is sufficiently close to 0 but value of g (0) is about 0.15 which is far greater than 0. g (0) goes to zero at about eta=25.

So  can I get rid of the problem?  

Is there a way to insert a table of content with the headers of the sections at the beginning of the document? (like in MS Word)

If I click on the link, maple should jump to the section.

It should be updated, if I create a new section or change the header.

My operating system is Mac OS X 10.6.4.   Lately Maple has been EXTREMELY tempermental in letting me "Save As a Worksheet"......I'm NOT talking about the "classic worksheet"

 

I try to save a file with a different name using "Save As A Worksheet" and Maple goes through the whole "Saving Worksheet" routine BUT NO NEW NAMED file is made!

This is very frustrating.....since it wasn't like this before.

Any ideas?

Hi! I am trying to solve this system:

 

 but I have a problem.

Hi everybody:

I have the following problem. I obtained an asymptotic solution of a hard problem. The final result is a Maple procedure with five arguments; this function has hundred of term and it works beatifully in Maple. However, we need to convert this solution to C or Fortran code and  I am not able to do it.

After the sentence: Fortan(functionname, optimize, output="filename")

I get the following answer

Error, (in PrintTarget) assigning...

Hi! I have a problem with the total PDE linear system:

F=F(x,y,z,w,h);

X1(F)=F[x]+F[y]+F[z]+F[w]=0;

X2(F)=x*F[x]+y*F[y]+z*F[z]+w*F[w] - h*F[h]=0;

X3(F)=x^2*F[x]+y^2*F[y]+z^2*F[z]+w^2*F[w] - ((z-x)*h+C*(w-y)/(z-x))F[h]=0;  (C=const)

The Poisson brackets are:

[X1,X2]=X1, [X1,X3]=2*X2, [X2,X3]=X3.

I'v tried to solve this system with pdsolve, but F=const is the only Maple's answer. But I am sure that this system has a...
