Hi
how can we write a same result n-times near each other


x:=3:
for i from 1 to 4 do       # here the 4 can be a variable and can change...
    x;
    od;
                                  3
                                  3
                                  3
                                  3

I need the result to come in that form  :    3  ,  3  ,  3  ,  3
and because the number of times can change i can't just easily write x,x,x,x;

thanks in advance

F := Matrix([[2, -1/2, -1/3, 0], [0, 6, 1, 0], [1/3, -1/3, 5, 1/3], [-1/2, 1/4, -1/4, 4]]); evalf(LinearAlgebra[Eigenvalues](F)); Gerschgorin(F)

Could you print A & F ?

Hello i would love some help with this code i need Maple to make an exercise guide in word automaticly the thing is that i don't know how to automaticly insert the plot in the word, i think there is no fprintf format to add images or plots maybe with exportplot? i really don't know; here is the Code is Basic for a starter student i just need the comand to insert the plot just that.
-------------------------------------------------------------------
fd:fopen("Graphs.doc", WRITE);
 for i from 1 by 5 to 11do
  if i=1 then plotsetup(bmp,plotoutput=plot1);
 a:= -50;
 b:=30;
 elif i=6 then
 plotsetup(bmp,plotoutput=plot2);
 a:= 50;
 b:=-30;
  elif i=11 then  plotsetup(bmp,plotoutput=plot3);
  a:= 2;
 b:=-3;
 end if;
 h:=(i*x^(2)-((3*a)/(i-42))*x-(i*b)/(-i+42));
  fprintf(fd,"the quadratic equation is: ")
fprintf(fd,"%q \\n",h);
 #`HERE IS WHERE I NEED THE PLOT TO BE`
  plot(i*x^(2)-((3*a)/(i-42))*x-(i*b)/(-i+42),x)
   end do; 
 fclose(fd);
--------------------------------------------------------------------
pd. i can't do it manually i need it to be automatic later i will add some inputs to make it even faster.

Hi, as I can't manage to copy and paste on mapleprimes, I would be glad to get a hint ...

Hello,
I am looking here for a tutor, that can help me doing some Maple V (5) programming.
I am a mathematic student and we use Maple programming.
I will be happy to pay a small amount of money for each exercice you help me doing,

if anyone is interested, please contact me here.

(The procedures that we usually have to write are for example:
 Newton-Raphson Method, Chebyshev Polynomial,...  I don't think it is hard for you.
Thank you very time for your time and your help.

How to find the nth derivative of (logx)/x  and (e^x)logx by using leibenitz theorem....?

 

 

 

Hello,

I would like to export maple inputs as xml code. The aim is to recover the semantics of the inputs.

I have tried without success with the Export Function.

Have you some ideas to export maple inputs as xml and with preserving the semantics of the input ?

Thanks a lot for your help

Maple function plot allows to build a linear plot for two vectors, when one vector contains X coordinates, another -- Y coordinates (similar to plot below):

Is it possible to build such a plot for several Y-vectors like this:

I want to solve the following differential equation


solve
(y''(x)=(λ*x* y[x])/Sqrt(-1+ x), y(x),x)


But do not know how to actually solve it. Any suggestion?

Determine wether the sequence below converges or diverges, and if it converges, find the limit.

{n^(1/n)}  

and,

{exp^n/n^4}

Thanks

hello guys i have 2 diiferential equations and i want to check a solution for that , how to do it ?

E and B are functions of r .

 

i want to put E(r)= r^a and B(r)=e^ar in equations.diff.mw

Hi all,

 

min/max command in Maple can return the minimum/maximum of a sequence or array.

 In my case, I want to find not only the minimum/maximum, but also where are them. How can I do?

For example, there is a squence [1,2,3,7,6,5,4].

Through max([1,2,3,7,6,5,4]), we can get 7.

But I still want to get "4" which is the index value of "7". 

 

Thank you.

 

can i use maple to get all the roots in a given expression?

 

for example: i have a expression "(2b+c)^(1/2)+c-(c-2b)^(1/3)"

and I want to get a list that contains "(2b+c)^(1/2)" and "(c-2b)^(1/3)"

 

is there any maple commands i can play with?

assume x,y is a real number and {x>4,y>4}, how can i get the supplementary set ({x<=4,y<=4}) of x,y in the real domain by maple?

Some of the Rotation Coefficients are not calculating properly.
