I tried > with(plots): with (DEtools); A:=phaseportrait(...); # equation and initial conditions depend on parameter s; phaseportrait works. All my attempts to make animation animate(A,s=-1..1,frames=10); with frames=50 resulted in errors Error, (in DEtools/phaseportrait) invalid specification of initial conditions Error, (in plots/animateb) Third argument must be a range in this case Any suggestions? Thank you very much in advance
I have been trying to understand the example examples/Optimization LSSolve section (at the bottom) and use it for different data and a different equation, i only want to find residues for omega_o, F, m and b not omega in the equation F/sqrt(m^2*(omega^2-omega_0^2)^2+b^2*omega^2) How do i just find residuals for these four unknowns only. Thanks
Hello to all users, I have a ode ode2 := (diff(psi(x), x$2)))-lambda^2*psi(x) = 0 The boundary conditions are that the value of the function at x(L1) = psi1 and the derivative of the function at x'(L2) = 0 (insulation cond for the heat problem). I can get the solver (dsolve) to work if I give a numerical value for L2: bcs2 := psi(L1) = psi1, D(f)(10) = 0 However I want it to work for a general case. Can this be done? Thanks, Arya
I am new to Maple, but i have done some basic graphing, scatteredplots etc. but I wanted to know if I can plot error bars in my graph? Is there any function or a way define in Maple 10 to do so? Help will highly be appreciated. Amini
Running into this problem, im trying to graph concentric circles (think planets) with a set radius and a set amount of time used to complete one orbit. I am using parametric equations with t being a value of time in terms of one complete orbit. However, when I try to graph these circles using plots[multiple] I get error codes. Heres my text~ We have our 5 planets, A - E orbiting around the sun affixed at the origin. We can easily graph these together to give us an idea of the orbit and time required to complete one. > plots[multiple](plot, > [0.71 cos(2.985074627 Pi t), 0.71 sin(2.985074627 Pi t), t = 0 .. 67],
i have a program to write and i dont know how to do it. if anybody could hwlp me cheers. Q implement a computer program which fora given positive integer n, a given square matrix A of order n and given vector b which n components, decides whether A is a band matrix with p=2=q and in the positive case solves the system of equations Ax=b by simplification of Gauss Elimination for a band matrices with p=2=q
Please could somebody explain the process Maple uses to factor integers so quickly? Thanks Matthew
What happened to my post in this thread; http://beta.mapleprimes.com/forum/maple-doesnt-find-solution-but-plots-the-solution#new I used the HTML conversion tool to upload a worksheet. When I enter the page now, I can download the worksheet, but the in-line all I see is alternating Bold and Normal text saying "Maple Equation". Am I the only one to see this, or has my upload failed? Does this have anything to do with the New Mapleprimes Filemanager MapleNet implimentation? I've also got a signature, but do not see it after my comment? What have I done wrong? Thank you!
Hello everybody, I have Maple 9.5 and Excel 2003 on my laptop. Unfortunately, I always get a runtime error 53 when trying to load the Add-In, telling me that the manager cannot find the Add-In although it is loading the toolbar for Maple within Excel. Can somebody help me solve the problem? Is there a patch available for this? Cheers, Fox
HI. I hope anybody can help me. I have in parametric form a volumetric element in space: >restart: >A:=(r,theta,phi) -> [r*sin(theta)*cos(phi),r*sin(theta)*sin(phi),r*cos(theta)] where: r in [1,3], theta in [Pi/4,Pi/3], phi in [0,3*Pi/4] I know want to plots this as an volume element in maple if possible. This means, that every surface has a grid. Can anyone help me with this one? I only seems to be able to plot planes i maple? //Sentinox
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 Victor Ivrii
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 ung├╝ltige 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.
