Hello, I am attempting to import a .pdb file into Maple, as part of converting some Mathematica code to Maple.  I need something that that can accomplish something equivalent to the Import command in Mathematica.  I have tried using readdata, ImportData and fopen with little success.  If anyone has any suggestions, that would be of great help.

The label for the horizontal axis refuses to be printed no mater what I tried. I can insert, change and manipulate the vertical axis label but not the horizontal. I don't know what else to try.

Hello

Very broad query, but I was wondering if anyone has experience of converting Mathcad code to Maple (v13)? I have a series of files that I am looking to re-code in Maple but am having some issues with equivalent syntax etc. The code varies from simple work to more complex studies with variants of FFT (including complex values).

Any help would be most welcome.

Regards

Lester

Dear Sir

I want to solve system of algebric equations using matrix

can you help me to do that

> restart;

I guess this is trivial, i just want Maple to apply the convert-to-product-rule:

i typed in sin(x)+sin(x+Pi/3) and looked for some related command in the context menu, but expand,combine or simplify or else didn't work.  What did i miss ?

Hi

I have this sequence which I would like to find an equation f(n) (using RSolve?).

the independant variable is n.

n=4,5,6....inf (incrementing by 1)

f(n)=2,3,3,3,4,5,5,5,6,7,7,7,8,9,9,9,10,11,11,11,12...etc

(an even number followed by three subsequent odds and so forth)

thanks!

y =

I cannot solve this for i. When I use maple I get a big result with a RootOf function that I don't know how to handle. I've looked around and I cannot find anything that will help me.

Can someone please show me how to solve this?

Thanks!

 I would like to pay attention of the Maple Primes Users to a Sergey Moiseev application. This is a Maple package on orthogonal expansions, which can be implemented in Maple as a usual package with a usual help. It  has Community Rating 4 stars.

Hello.

I have a problem with creating eigenvalues of a 14x14 matrix.

when i execute "LinearAlgebra[Eigenvalues](A)" there are only results like "-3.2211+29.1111I"

The problem is the 'I' at the end. I need numeric values for plotting or stuff like that.

Wheres my mistake? I have no clue.

Im looking forward to any suggestions! At the bottom...

It seems to me that the page on Unanswered Questions contains questions which are actually already answered.

An example is Sorting a list of xy pairs, on which one I spend some time yesterday preparing an answer, until I discovered that it had already been answered (one of the answers being completely analogous to the one I had prepared).

A certain "competitor" to Maple has started offering a "Home" Edition of their product for a very attractive price...I use Maple at work, but love to tinker with individual research.  Supposedly, this edition is the same full-featured product as the commercial and academic versions.  A "Home" Edition of Maple would be *awesome*.  I'm not prepared to jump ship to that "other" product, given the knowledge capital I have of Maple, but I've started entertaining the idea...

Hello everyone,

I want to create a loop in descending order like this: for i from 100 by -0.01 to 0 do ....

I wrote functions trying this logical solution but nothing, please help, it's very important to me to get the answer as soon as possible.

Thanks in advance!

E.g. I have three lists:

L1:=[1,2,3];

K1:=[4,5,6,7,8];

K2:=[7,8,9,10,11];

and if needed I have a fourth list

ALL:=[L1,K1,K2];

Now I´d like to add 99 to all lists whose name contains a 1 and add a 999 to all lists whose name contains a K.

The problem is, when I refer to the elements of ALL, Maple "thinks" I refer to the list. But how do I tell Maple,

that I want to refer to the lists´ name instead of the list itself ...

i'm working on a short program to put random points on a sphere , but i have some difficulties :
 i consider a sphere  where  i choose  n  points  with  "randpoint" then i plot it but it doesn't work if someone can help me to correct my program

here is the program :

>with(geom3d):
> with(plots):
> s2:=sphere(s3,x^2+y^2+z^2=1):
> sphere1:=(x,y,z,R)->[x+R*cos(phi)*cos(theta),y+R*cos(phi)*sin(theta),z+R*sin(phi)]:
