In Maple 10 (patched to 10.03), there seems to be a bug in Typesetting[Suppress] when the function name is a Greek letter name. For instance the code interface(typesetting=extended): Typesetting[Suppress](eta(x)): diff(eta(x),x) = eta(x); should typeset like   η' = η or perhaps    d η / d x = η (depending on your "prime" settings). But one actually sees    η' = eta which is incorrect, or at least inconsistent and unexpected. More careful tests show that the whole Greek alphabet is affected similarly, apart from pi and zeta, which are handled slightly differently though still incorrectly.

Installing 9.03 patch over the CD Maple 9.01 version (Win XP SP2, 2GB RAM) I have met, apparently, the same java-RAM problem (Standard does not start) that this CD version has before replacing maplew9.exe with the version of the FAQ area of Maplesoft site. But this maplew9.exe replacement does not patch the patch. So, I wonder whether there is a solution for 9.03 or I should turn back to 9.01.

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...

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??????????????????????
