If I have two different plots constructed with plot command I can display them simultaneously:
> F:=plot(...);
G:=plot(...);
display(F,G);
However, if I try
> with(DEtools):
F:=phaseportrait(...);
G:=phaseportrait(...);
display(F,G);
Maple 10 returns an error that display requires plot!
Is there a way to display simultaneously two phaseportraits?
Thank you in advance

Hi,
is there a way to install the maple toolbox for labview under LV 8?
During installation process i receive an error message that LV 7.1 is necessary.
Thanks for any help,
Tom

The following seems to run endless (WinME, M10.02 classical interface):
Int(2.9992571251988*(kappa-.89988751406074)/Pi*
exp(3.3571035419740-12.0624756920228897*ln(kappa))*
BesselK(1,26.1571648648044217*(.13147587176957e-1+(-.57683186342273e-1+ln(kappa))^2)^(1/2))/
(.13147587176957e-1+(-.57683186342273e-1+ln(kappa))^2)^(1/2)/kappa,
kappa = .89988751406074 .. 4.0);
evalf(%);
I did not want to massage it by hand (as the fct may change and actually I
want the upperbound to be infinity). The reason can not be the slow numerics
for Bessels (as an external DLL with brute callback gives the result slowly,

That kills my Maple ( M10.02 on WinME)

restart; _EnvExplicit:= true;

Eq:=0 = 'mu + delta*sqrt(alpha^2-Theta^2) - sqrt(alpha^2-(Theta+1)^2) ';

[solve(Eq, Theta)]:

sols:=%;

giving the system message:

CWMAPLE verursachte einen Fehler durch eine ungültige Seite

in Modul CWMAPLE.EXE bei 017f:00459d0b.

Register: blablabla

If I prevent output by "sols:=%:" (using a double point) it is ok and one

sees that it would produce ~ 5000 pages ( = length(sols)/80/60 ).

Could be that one reason?

I want to call a procedure or function by clicking a button. How to call a procedure from Maplet Builder: Evaluate -> function? And where I have to write this procedure: to save it - in Maple 10 worksheet like file *.m in the same folder where file *.maplet is?

I am converting a complex worksheet from linalg to LinearAlgebra, and
discovered what is to me a serious problem. With linalg, one could use
the basis(A,colspace) command to give a basis of the column space consisting of columns from the original matrix, guaranteed to be in the order in which they appear in the matrix. This is useful in extending a spanning set of a vector space to a basis of a larger space, and allows one to determine exactly which new vectors need to be added. However, the ColumnSpace(A) command in LinearAlgebra does something quite different. It gives a basis of the column space which does not preserve this order, and does not even use the original vectors.

I have two matrices, and I want Maple to test and see whether they are different to each other (as part of a for to while loop -i.e. it will keep looping until the matrices are the same). However, even when they are identical, it returns a value of true to evalb(A <> B). What can I do?

When I try to run this particular programme, it pops up and tells me "Clarify Expression" - "Parts of the expression are ambiguous. Please select one of the suggested meanings." However, before the suggested meanings it quotes the line of programming that this happened on. When I made the programme, I did it line by line, so I know what the suggested options are, and which one I want. However, now the line of programming is such a big block of text that the window goes completely off screen. There's no way to resize it, and I can't move it high enough to see the options. What can I do?

I have installed Maple 10 Build 190196 and I wish to retain the settings and preferencess of Maple 9.51 Build 963582. Which files should I retain from Maple 9.51 before I uninstall it? Where should I place them to retain the 9.5 settings in 10? Thanks, Bill

I have the fuction F/sqrt(m^2*(omega^2-omega_0^2)^2+b^2*omega^2 and i need to fit data to it using the LSSolve command, i have no idea how to do this any help would be much appriciated. thanks.

I would like to hyperlink or insert acces to other program files. I can do this in MS Work and Scientific Notebook. Ex. I can execute Vpython simulations, audio files, saved web pages, etc. Thanks

Hi, can you advise how I can draw geometry objects like circle, triangles, polygons, angles in triangles, etc accurately -- I need the gepmetric shapes to be to-scale -- in other words, if I need an angle at 50-degrees, I don't wish to eye-ball it, but I really need it to be 50-degrees. Thanks!

Hello, i'm a father and my son is at school, he asked me if I could give him some help on his maple project. He has to write a pascals triangle using List, is there anyone who can help.Thanks, Ronald.

Hi, I would like to find the critical points of a formula like: f(x,y)= 5e^((-x^3)-xy/3-y^2/3)cos x cos y But I don't know how to do it, can someone help me? regards, Patrick

Hello Memebrs,
I want to write a code in Matlab, that will find a best fit. I have 4 columns of values. The Red, Green and blue values and in the fourth column the temperature values. I want matlab to intelligently find me the best corelation between the RGB values and Temperature. Any pointers as to how i can go about doing this. Ofcourse the main goal is to get the best fit with minimum error.
Thanks in advance..
