The following interactive worksheet gives you the possibility to plot functions in 2D and 3D. There is also an interactive version available on the MapleNET - Server. You find it here. You can also download the worksheet here and run it in your Maple.
I will try to publish further versions with more possibilities to plot in the next weeks.

Hi, I have a big Problem, I have experimental points which can be describe by a complex function. I can get data points of the real part and of the imaginary partof the function: REAL PART: [0.1000000000e-1, 5.1328], [0.2000000000e-1, 5.1295], [0.4000000000e-1, 5.1246], [0.8000000000e-1, 5.1207], [.1600000000, 5.1135], [.3200000000, 5.1031], [.6400000000, 5.0936], [1.280000000, 5.081], [2.560000000, 5.0688], [5.120000000, 5.0582], [10.24000000, 5.0481], [20.48000000, 5.038], [40.96000000, 5.0281], [81.92000000, 5.0174], [163.8400000, 5.0051], [327.6800000, 4.9908], [655.3600000, 4.9733], [1310.700000, 4.9518], [2621.400000, 4.9254], [5242.900000, 4.8927], [10486.00000, 4.8534], [20972.00000, 4.8077], [41943.00000, 4.7539], [83886.00000, 4.6957], [167770.0000, 4.6343], [335540.0000, 4.5702], [671090.0000, 4.5076], [1342200.000, 4.4478], [2684400.000, 4.3949], [5368700.000, 4.3688], [10000000.00, 4.288]

This tip comes care of Dr. Michael Monagan at Simon Fraser University. Represent your sparse matrix as a list of rows, and represent each row as a linear equation in an indexed name. For example:

A := [[1,0,3],[2,0,0],[0,4,5]];

S := [ 1*x[1] + 3*x[3], 2*x[1], 4*x[2]+5*x[3] ];

To compute the product of the matrix A with a Vector X, assign x[i] := V[i] and evaluate. This can be done inside of a procedure because x is a table.

V := [7,8,9]: for i to 3 do x[i...

This was a topic suggested by a user. It's intended to collect useful tips and techniques to increase Maple performance.

To anyone: Will someone provide maple syntax to plot the following lines f(x), x=a, x=b from x=c..d where f(x) is an explicit function and x=a and x=b are vertical lines and the extend of the graph from x=c to x=d. This should give me the graph of the 3 equations from x=c to x=d. I tried implicitplot, graph it led me nowhere. Many thanks PV

Ten days playing with Maple has proven that skills in one system don't necessarily translate to another. I have encountered a number of frustrations which are not so much a problem with Maple as my inability to match the subtleties of the new system. Some of the issues I have encountered:

• periodic locking up of the interface in document mode (this may be due to something I am doing wrong)
• getting used to the maple syntax and command list (it is further than the syntax of Mathematica than I originally suspected yet similar enough to completely mess me up)
• occasional odd state like behavior (which is, again, probably due to my ignorance than a problem with Maple)

These are the notes of a new Maple user attempting to come up to speed in, what is for me, a new algebraic manipulation tool. I am looking at the tool not so much as an engine for solving problems as much as I am interested in using it as a tool for teaching advanced physics concepts to students in the secondary school arena. Right now I only seek to use it as an aid to building better presentations for the students as well as supplying a dynamic environment for solving problems for students in my class.

I am just a beginner to use Maple and now I have a second order linear equation with boundary conditions to solve. I want to get the numerical solutions and plot the solutions. However, I have tried many times, and still do not get the solution. So I want to ask for help. my eqaution is simple but just sort of long. y"(x)=4-8(1-2/r)(1/r**3+1/r**2), here r=43.48arctan(0.05x-1.23)+41.1, The input of my program in Maple is: restart; sol:=dsolve({diff(y(x),x$2)=((1-2/(43.48*arctan(0.05*x-1.23)+41.1))((43.48*arctan(0.05*x-1.23)+41.1)^(-3)+(43.48*arctan(0.05*x-1.23)+41.1)^(-2))*8-4)*y(x),y(-2)=-0.65,y(40)=-0.11},y(x),numeric);

How do I use Matrices to solve linear equations?

In response to a question about collecting symbolic powers of polynomials, I suggested a few lines of code that solved the particular problem. Following is a procedure that enhances the technique to mimic, to some degree, the abilities of Maple's collect procedure, which handles integral powers. This enhanced version can take a list of indeterminates. It also permits use of an optional third argument, func, that is applied to the collected coefficients of a power.

When u mean maple, is it maplestory the game??????????????????????

I'm using Windows XP prof. edt. and Maple 9.5 I installed Maple and it is running properly but there is an important problem with the user-interface of Maple ; For example, scroll bars,check boxes,sliders. . . can not be seen on the interface. Therefore, for instance in the "Options", I can not understand whether a checkbox is checked or not. (The most important part of the problem :( ) I've already installed Java VM (jre1.5.0_06) What should I do ?

For no reason other than curiosity, we have a new poll ...
