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

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 created a small procedure to select a random number from a list. 

pickrand:=proc(num,list)
local a,b,i:
randomize():
a:=nops(list):
for i from 1 to num do
  b||i:=rand(1..a)():
end do:
seq(list[b||i],i=1..num);
end proc:

a:=[3,6,7,8,3,6,5,7,8,9,1,2,3,4]:

pickrand(3,a);

          [8,8,5]

Now it's possible that the two 8's are in two different positions of...

I can't seem to find anything on cluster anlaysis (kmean etc...) in Maple's help.  I thought graph theory might contain something close but not really.  I haven't tried but I suppose it shouldn't be too hard to create a few procedures for such things?  Can someone provide a few examples?

Of the 3 M's Maple seems to have left this one out?

Hi all,

I was wondering if their is a way to import c++ output to maple 12 as I need to plot my output.

If yes, I will appreciate if someone can guide me through the steps.

Thanks 

do u have any manual procedure , may be in vedic mathematics, to check out if  large number like 600851475143 is a prime???? also to find out the posssible factors for that number....

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...

I tried to skip some iterations of a do loop, by using the following code:

for i from 1 to 19 do
if i=8 or i=16 then
  next
end if:

...

Unfortunately Maple just accounts for the i=8 but not for the second condition i=16.

How may I specify more than one condiions in an if statement?

I´d like to compute some sums where x ranges to infinity.

How may I compute that in Maple?

sum(ln(x)/((x)^(2)+3*x+2.),x=1..infinity):

didn´t work.

add(ln(x)/((x)^(2)+3*x+2.),x=1..10000):

is possible and though I know the limit of the expression

limit(ln(x)/((x)^(2)+3*x+2),x=infinity) is known and zero, I have no idea of how to compute the sum to infinity from the first place.

When I execute a do loop and an invalid output shows up, Maple breaks the loop.

Is there a way to tell Maple to show me, where the error occured, but nonetheless execute the loop to the very end?
