I am struggling with the new LinearAlgebra package and I want a procedure for the vec operator (just stacking the colums of matrix r by c into a (r*c) by 1 columnvector. For only extracting two columns the following commands work well: A := Matrix(5, 5, symbol = a); Matrix([[Column(A, )], [Column(A, )]]); but there must be a simple procedure for doing this for a converting a large matrix into a column vector. Any help would be appreciated. kind regards, Harry Garst
I am working on a program that creates symbolic algebraic expressions. I'd like to be able to "export" these to Maple. Ideally I'd like to have a menu option "Send to Maple" that would either start Maple or find an existing running version. It would then simply paste the expression in Maple syntax into the open UI.
The OpenMaple API seems to only give access to the kernel which appears (and rightly so) to know nothing of the UI. Is this the case? Is there any API that would allow me to paste to an open Maple window?
I tried enumerating all open Windows via MS Windows API functions. But since the Maple UI is Java based I couldn't get a pointer to the window...plus this seemed to be a pretty hacky solution to me.
# equation and initial conditions depend on parameter s; phaseportrait works.
All my attempts to make animation
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
How do i just find residuals for these four unknowns only.
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?
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?
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!
I'd like to write a maple TA question involving a sketch.
There are standard tests used to evaluate whether the sketch designed by the student is correct, such as :
There is a certain tolerance in these tests. If the sketch aproximately goes through point (0,1) in the previous example, it will be considered correct.
My questions are :
What is this tolerance ?
Is it possible to set this tolerance ?
Is it possible to artificially create a tolerance factor (with something which would look like :
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?
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:
However, if I try
Maple 10 returns an error that display requires plot!
Is there a way to display simultaneously two phaseportraits?
Thank you in advance
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,
