Dear users,

I have a Maple file to evaluate the shape functions on hexahedrons and to save the results in a .cpp file. However, the execution time is very long and when I do not loose the connection with the server, I ran out of memory (I have 32GB!!). So, I very keen to hear some tips on how to optimize it! I am sure this computation is simple enough for the Maple powerful and I quite sure there are some tricks to optimize it! The code is below.

Thanks in advance!

Hi all,

C:=2:

solve({K*(K-1)>6*C-2,K>0},K,useassumptions) assuming K::point;

It does not exacly give me 'integer'.

for C from 2 to 10 do

isolve({K*(K-1)>6*C-2,K>0},a);

end do;

gives me pretty much what I am expected to see. The positive smallest (ceiling) numbers, 4,5,6,6,7,7,8,8,9.

Is there a way to obtain a "neater" output?

Say I just want a sequence (list) of 4,5,6,6,7,7,8,8,9.

sorry if the wording is bad. first time on the forum and first time using maple. basically i'm switching from a graphing calculator to this and don't know any "shortcuts" or anything. answering the original question and any other tips/tricks/advice/etc you may have to offer is greatly appreciated. 

(i could always just use the formula but where's the ease in that?)

I would like to Maple develop mathematical exercises as do Bagatrix and Algebrator packages as examples. What think you?. The primary and secondary students learn better if they observe the procedure for each year of calculus. I'm sure Maple care enough about the issue and expect changes in future versions.

Hello,

1) I would like to ask how I can force Maple to explicitly evaluate a summation over repeated indices. As an example: I would like to do a very simple thing, namely to evaluate the Lagrangian of a free particle in let's say cylindrical coordinates, as follows:

restart:
with(Physics):
with(Physics[Vectors]):
Setup(mathematicalnotation=true, dimension=3):
Coordinates(X=[rho,phi,z]);

Setup(metric = drho^2 + rho(t)^2*dphi^2...

Today maple is being used as a helpful tool, but teachers should learn mathematics in depth, and in this way use the primitive concepts of mathematics. This very well use the algorithms that reduce the lines of code in the resolution of a problem, but it is very necessary to use command to demonstrate theorems, since inico to completion, and then be tested with new commands that meet on a line of estio the problem code. What do you think about the development of mathematical procedure, using native commands?

Aquí le dejo otro de mis trabajos hechos con puro matemáticas, creo que me parecio por demás plotear las alturas y medianas ya que eso se realizo en la recta de Euler.

Hi,

I have always been experiencing problems using a university server. It runs Red Hat 6.4 (Santiago) and Maple 17 X64.

The problem never occurs on Windows 7 SP1 X64 with Maple 17 X64.

Only reason I want to use the university machines is that it's "faster".

I had raised...

Hello all,

I was wondering if the following thing is possible and how to do it:

I have an assignment, to teach about circles and its equations. What I want to do, is to create some sort of application, that get as input the radius and and the other two parameters of the general equation of a circle, and plots it.

Now, to plot a circle using Maple 17, is fairly easy. But how do I create a graphical bar or other alternative...

LegendreP(m-1/2, l+1/2, coth(x))/sqrt(sinh(x))

I want to calculate the series about x=0 but I get the error 

Error, (in MultiSeries:-multiseries) need to determine the sign of, 2*m

What problem does maple encounter here?

I tried assume(m>0) and then I got the error

Error, (in MultiSeries:-multiseries) need to determine the sign of, 1-2*m

Is it possible to use printf to get math 2d output? For example, I'm writing a loop computing Riemann Sums.

f := x-> x^2; a := 0; b := 1; for i from 1 to 5 do printf("f(x[%d])=%a",i,f(a+i*(b-a)/5)*(b-a)/5); end do;

I would like the output to look nicer. Thanks in advance!

We are a school with more than 600 Maple users, we have 3 Mac mashines, different types that all give us the same problem. 

When installationi problems occur we use this method.

Restart MAC computer

uninstall JAVA

Restart MAC

get new version of Java - and install.

Restart MAC

get MAPLE 17 from homepage and install. 

We get a grey window where we can see next, but nothing else.

All users have adminstrative...

I was trying to get the labels and titles in a plot to be typeset using LaTeX fonts on a computer running SUSE 12.2.  Everything worked on a Windows 7 computer with the LaTeX fonts installed.  Maple 17 would use not use the CMU Open Type fonts that were installed on the Linux computer.  After switching in the CMU True Type fonts for the CMU Open Type fonts, everything works properly in the attached worksheet on the Linux machine.

I executed a Jacobian function as follows X:=Jacobian([a,b,c,d,e],[y[1],y[2],y[3],y[4],y[5]])
a,b,c,d,e are initialized expressions/equations and
y[i], i=1..5 are the variables and I got the result below

Hello all,

As in title I am really bothered with result in floating number obtained from laplace(expr, t, s).

I have a target to laplace and the laplace() gives me result with floating numbers.

(ex. laplace(diff(diff(f(t),t), t), t, s) = laplace(s^2. * laplace(f(t), t, s) : the period after 2 is annoying)

How can I avoid or do some conversions to kill the periods?
