Hi, all, I have a question, how to expand a multivariate polynomial, like this: F := [1-(x[1]-1)^2]*[1-(x[3]-1)^2]+[1-(x[1]-1)^2]*[1-(x[2]-2)^2]+(2*[1-(x[1]-1)^2])*[1-(x[2]-2)^2]*[1-(x[3]-1)^2] when I used expand(F); the result is the same as F itself, nothing changed. Whether there is some way to expand the multivariate polynomial into a completely expanded form, like: 2*x*y^2*z^2+2*x*y^2*z+x*y*z^2+x*y*z+x^2*z^2+x^2*z+x*z^2+x*z+x^2*y^2+2*x^2*y+x*y^2+2*x*y thanks.

Hi can someone please help me. I am trying to save a list to a file but the code below saves the list with spaces. So when i open the file they all have spaces after each number(see below). How can i save the list as it is?

Hi everybody, Using pdsolove(SyPDE, BIC, numeric), I have to model propagation of two waves , u(x,t) and v(x,t) , in two elastic test rods that are in contact. The problem are boundary conditions at the contact surfaces: values of forces and strain are equal at the first rod right end and at the second rod left end: D[1](u)(l_1,t)=D[1](v)(0,t) and (u)(l_1,t)=(v)(0,t) Maple can't do that. Should I put in code some transitional Maple expression or function for force and strain, like, for force X:=(delta*x)/l, in order to get this: D[1](u)(l_1,t)=X, D[1](v)(l_1,t)=X,
Hi, I want to plot all points (x,y,z) with the properties: z = x*y x = sqrt(9-y^2) How can I do this? Thanks.

u:=Vector([1,1,-1]),v:=Vector([2,0,-5]),w:=Vector([5,1,-11]) (Vectors are by columns)

How can I find a basis for the subspace spanned by {u,v,w}.

Hi, I'm new to Maple,

 

I need to draw:

j:=x->1/sqrt(2*x-x²);
           1      
x -> --------------
     sqrt(2 x - xᄇ)
I found the integer who is :

As soon as my matrices are larger then 10 by 10, Maple doesn't show them. Instead I get

Vector(4, {(1) = ` 14 x 14 `*Matrix, (2) = `Data Type: `*anything, (3) = `Storage: `*rectangular, (4) = `Order: `*Fortran_order})

How can I change this?

Thanks!

Hello,

I'm a newbie with Maple12 (MacOS) and unfortunately not able to solve my problem on my own, that's why I'm asking you for help:

After importing an 8x8 matrix from Excel into Maple I cannot get the eigenvalue of my matrix. Error message:

Error, (in LinearAlgebra:-Eigenvalues) invalid input: LinearAlgebra:-Eigenvalues expects its 1st argument, A, to be of type Matrix(square) but received C

Why is the function Eigenvalues expecting an square Matrix???

here are my files:

Hallo,

I´m trying to create a 3D-plot of the following data

0.25Y               0.5Y               1Y               2Y               5Y               10Y

Hello,

 

How can I combine two plots so that one is above the other and they have the same x-axis.

 

Here's an example of what I want.

 

 

I tried array of plots, but in this case each plot has its own axes and they are side by side horizontally.

 

Any other suggestions?

 

Thank you

On some Linux distributions, the default font (Lucida Bright at size 12) for text mode in Maple's Standard GUI doesn't look as good as it might at the default magnification.

Here's a screenshot of Maple 12 and some text in a worksheet (on my very old Fedora Core 2).

Notice how some letters look odd. The "i" and "s" are mismatched, as are the "u" and "c", etc. The screenshot may not do full justice to its ugliness. That is with Maple's option for font antialiasing enabled (though it wasn't improved by disabling the antialiasing -- those letters' sizes were still mismatched).

This is with Lucida Bright, which as I gather is the "recommended" font for a Java application that is intended as cross-platform. That is used at size 12 as Maple's default style for text mode (on Linux).

So I installed the "Microsoft TrueType core fonts", by following the instructions here.

My old Linux FC2 X server can handle TrueType fonts, as I believe  most  modern  Linux distributions can.

Now I get the following look, first with and then without font antialiasing enabled. It is much improved.

I don't know how the default appearance on other, more modern Linux distributions looks. Perhaps the Lucida Bright 12pt font appears more pleasing on new distributions using the stock fonts. Feedback is welcome.

Hi,

I am dealing with the following problem, which has extensive symbolic computations. It was taking extremely long in MATLAB so I thought of Maple. It turns out that Maple is also taking pretty long time. Is there any way to accelerate this in Maple (or in MATLAB).

I am attaching a two-line Maple code (Thanks Alec for the previous help)

u := (1-cos(x)):
for i to 10 do u := u+int(subs(x = t, diff(u, [`$`(x, 2)])+u-A*(1+2*u+3*u^2+4*u^3))*(t-x), t = 0 .. x) end do:

where A is a constant.

Hi,

I am new to Maple and wish to convert the following simple code written in Matlab to its equivalent Maple.

------------------------------------------------------------------------------------------------------------------------

syms x
F=x^2;
for i=1:5
    G=F+int(F);
    F=G;
end
