Just curious if there are any best upgrades to a computer to improve the speed of Maple.  Here's my issue.

It could be perhaps that I am just being bogged down by my video card.  When I have many plot displays open or a large plot structure with many points Maple really bogs down.  I think it's most likely my video card but I would like to hear some thoughts on this. 

It is a fairly old computer by todays standards ( single...

Dears,  I have a system of linear equation A*X=B   where A matrix 607x400  & X vector  400x1 and B vector 400x1

where A not square matrix. To sove,  I do

(A^T)*A*X=(A^T)*B,

Let   D= (A^T)*A        D  square matrix

then

D*X=(A^T)*B,

the solution is

X= (D^-1)*(A^T)*B.

could any one help me to do this by maple and cut the resluts in...

How do I graph several level curves of the function f(x,y) = ln xy with maple.

I am trying to get maple to print output whilst running a procedure. This works fine with Maple 11 under Mac OS 10.4, and it also works with Maple 11 under Mac OS 10.6 when using the command-line version.  However, it does not work when running the GUI version of Maple 11 under Mac OS 10.6.  Has anyone found a way around this problem?

Dear my friends

Hi

I want to calculate the high-order approximant of taylor series or expansion of f(x) as followings;

g:=taylor(f(x),x=1,60);

g:=expand(f(x));

in which f(x) is a very large expression with respect to x. for example, assume that

f:=x->sum(n*x*sin(n*x),n=1..1000);
g:=taylor(f(x),x=1..60);
Above...

I am working with a 3 dimensional vector partial diff eq that resembles the Helmholtz equation, but there is a curl of the vecotr field as the middle term.

ie-->LaPlacian(F)+2beta*gamma^2*curl(F)+gamma^2*F = 0

Anyone have knowledge or references for me to look over to solve this equation?

Hi, I'm new to Maple and I'm trying to use it in some frequency domain convolutions analysis. At the moment, I'm just tying to organize my work and for this I need to perform some simple variable changes on multiple integrals.

I've started like this: 

> conv:= (x,h,t,tau) -> unapply(int(x(tau)*h(t-tau),tau),t);

> Y[1]:=omega->H(omega)*X(omega);

> with(IntegrationTools):

> Y[2]:=conv(Y[1],Y[1],omega,sigma1);

Hi,

I'm new to Maple.

I'm trying to solve the folllowing systems of equations:

Y= 2x^2-5x+ 3, y= x^3 + 4x -3

However when I try and solve it I dont seem to get a straight answer for X and Y. I've been reading other examples and they all give plain values for x and y.

hello everybody

I need help please

in some forum i found this problem

find a number "abcdefghijklmnopqrstuvwxyzâôîé" with 30 digits if we renverse it

it will be equal 

(éîôâzyxwvutsrqponmlkjihgfedcba)/4

Just a small issue with how you insert a ^ (caret, wedge, circumflex, arrow, hat, what have you), / (forward slash), or * (star, asterisk) as a literal in a comment in Maple.

In regular code, it works fine;

Typing \_ produces _
Typing \^ produces ^
Typing \/ produces /
Typing \* produces *

In a comment, only underscores work as expected.  The caret, asterisk and slash leave behind the escaping backslash, which you will have to go back and delete yourself.

I was writing problems about the bisection method and decided to use the Maple routine Student[NumericalAnalysis][Bisection].  The problem I wrote generates a cubic with all three roots in a somewhat random interval.  Students are then asked to find a root to a given accuracy using the bisection method.  If one does not hit a root, the Student[NumericalAnalysis][Bisection] routine gives the desired answer.

A problem arises when the bisection algorithm...

1. I have a Matrix V as following, and I found that Determinant(V,method=float) can not work. I use Maple12. Please help me , thanks.

2. also, in some calculations, I found Determinant(V,method=float) and Determinant(V,method=minor) gave different result. Anyone can tell me why?And which method is right?

V=[[0.2412702414,0.4868267037+4.770943828 10^(-17) I,-0.3582351644-3.597026404 10^(-14) I,0.8897131421,0.3035225208,0.2809455226],[0.5973344699,-1.205280722,1.019534434+1.083003890 10^(-16...

In a cup run and CuI crystals PbCl2. Did four works of solubility: pKCuI = 11.96, pKCuCl = 6.73, pKPbCl2 = 4.29, pKPbI2 = 8.19. You have 4 unknown concentrations in the solution, but 5 equations (which?). Can you explain what will happen? Documented with calculations.

Recently I was looking at an algorithm in one of Knuth's books.

The algorithm is described in steps with many of the form 

if condition 1 then goto step 7; if condition 2 go to step 8, 

etc.

I managed to write up the algorithm by making each step

a procedure, but had trouble with handling global variables.

Is there in Maple some standard method for dealing with such algorithms.

A friend tells me...

Hey,

I've been running the following program in a maple worksheet and it has worked fine.

Now I want to run it on an Ubuntu machine that has some extra computing power to get through a big data set.

However I get strange "Incomplete Quoted Name" errors, even when I have no quoted names in my input at all.

This is just alittle bit of the output I'm getting:
