Hi everybody,

I have a little problem with Maple 14.01:

I would like to export a figure created with plot3d as an eps file. I do so by simply right-clicking on the figure and than on export -> encapsulated postscript. The problem: it does not work properly:

With Maple 12, I get a 2mb large vector graphic. If I export the same figure under Maple 14.01, the file is only 148kb large und not a vector graphic - when I open it with Inkscape, it just looks like an ordinary jpg-picture.

1.For win 8, does there exist an arm version maple in future?

2.Will it possible to use gpu acceleration for symbolic computation in maple?

I have 8 equations (eq1, eq2, eq3, eq4, eq5, eq6, eq7 and eq8) with 8 varibles A1[n], A2[n], C1[n], C2[n], B2[n], A[k,i], D2[n], A[0,i] and where n=1..nn, k=1..nk, i=1..Q

I have some difficulties to get the matrix form AX=b

Thanks in advance for any help

I attached my maple code

piers.mws

Would much value shared experience or solutions on this

Thanks

How to solve a set or a system of differential equations in maple for motion with Schwarzchild metric?

************** Schwarzchild metric *****************
with(tensor):
coord := [t, r, theta, Phi]:

g_compts:=array(symmetric,sparse,1..4,1..4):

g_compts[1,1]:=1 - 2*G*M/(r*c^2):
g_compts[2,2]:=-(1 - 2*G*M/(r*c^2))^(-1):
g_compts[3,3]:=-r^2:
g_compts[4,4]:=-(r^2)*sin(theta)^2:

g1 := create([-1,-1], eval(g_compts)):

Hi. I wanted to figure out how to plot a boundary value problem in Maple. It is a nonlinear, fourth order ordinary differential equation with four boundary conditions. The BVP has the form (d⁴/dt⁴)-3(d²/dt²)(d/dt)=0, with boundary conditions x(0)=0, x(1)=60, (d/dt)(x)(0)=0, and (d/dt)(x)(1)=0. Thanks.

I am a retired physicist persuing independent mathematical research and don't fit into any of Maplesoft's four user catagories.

I am trying to develop a new finite element method for incompressible fluid dynamics in 3D. I must derive four vector functions which are mapped into the 84 degrees-of-freedom of the finite element. I expand each of the four functions in terms of multinomials with 192 unknown coefficients to be determined. I apply essential constraints to each...

I entered

animate(plot,[s*cos(Pi/2*(1-t)),s*sin(Pi/2*(1-t)),s=0..1],t=0..1);

and received the error

Error, (in plots/animate) unexpected options: [s*sin(.5000000000*Pi), s = 0 .. 1]

This is to draw a radial line beginning at 12 o'clock and ending at 3 o'clock.

I could get it to work as

animate(plot,[tan(Pi/2*(1-t))*x,x=0..1,view=[0..1,0..1]],t=0..1);

though.  But the length of the line is not fixed as I require.

I can solve a [0,1] linear programming problem by using:

LPSolve(Ob, con, assume = binary);


I managed to solve [-1,1] linear programming problem by using the transformation
2*w[i]-1 ie   2*0-1=-1 and 2*1-1=1 as follows:

LPSolve(add(PP[i]*(2*w[i]-1), i = 1 .. NC)-add(Draw[i]*(2*w[i]-1), i = 1 .. NC), {add(w[i], i = 1 .. NC) = PS}, maximize = true, assume = binary);


Now my question is how can I solve a [-1,0,1] problem?
I tried to use:

Hi,

I'm quite new to maple and I'm not really sure how to go about fitting a curve to my data, I have inputed the data by doing;

data := [[1,3],[2,3].........[2,7]]

and then plotted it using a point plot. Now i know I need to fit a resonance curve using LSsolve but I dont know how to go about using that command. Could anyone please enlighten me.

Thank you

Dear friends,

I generate a table for n=1 to 3.

Matrix(  [ seq ( [n, n^2], n=1..3)]);

I would like to generate the same kind of a table for values of n= 1 to 3, 50, 100  and 1000.

How may I do it?

Thanks in advance for your help.

I am trying to obtain the points with equal value of a two variable function ,f(x,y), 0.01<x<0.99, 1.01<y<1.99. I tried to dsolve the problem but I have one equation, two variable and infinite answers . Ho can I get these points with interval of 0.01 and insert in a marix. Thank you in advance.

Hello everybody!

I couldn't find this question on the internet.. I hope for a answer here! I have to know this in 4 hours, and nobody here seems to be able to solve it. Thanks a lot in advance!!

What i'm trying to do is to solve these 10 variables. here is my maple:

I am in a class of combinatorics following two definitions are to be coded in Maple. I have done my best but could not. Kindly help.

Def 1:    Let M=[m_ij] be a matrix of type m×n, whose entries are subsets of a set A.
Def 2:    A set matrix M is said to be a partition matrix of set A if:

    1. m_ir∩m_is=φ, for every i,r,s, such that r≠s;
    2. m
