Good morning professor.

I am M.Anand working for SRIIT, as Assistant professsor in Matematics in Hyderabad, INDIA.

I request you to help me out in generating Maple procedures for conjugate gradient method & Preconditioned Conjugate gradient method as it is consuming much time  for me to find out every iteration individually to solve linear systems with sparse coefficient matrices which arises in Numerical Analysis.

Hi all,

seq(a[i],i=1..3);

Works fine.

seq(a[i],i=3..1);

gives nothing.

But if what I really want, is a ordered sequence

for i from 3 by -1 to 1 do

r:=[op(r),a[i]];

end do;

a[3],a[2],a[1]

What's the best way to get it? (apart from writing a loop)

I am trying to get DiffTutor to work in Maple17, using Worksheet mode, and it doesn't do anything.  Here is the code and the output.  I cut-and-pasted it and the output looks weird, but you can see that Maple didn't do anything:

restart:

Hi

I'm new to maple and maplesim and I'm trying to model a 6 DOF manipulator (IRB 140); derive its forward and inverse kinematics and control it.

I modeled the manipulator in maplesim and attached the CAD files, but I don't know how to derive the inverse kinematics!

I tried to define the end effector position and orientation symbolicly, by putting sympolics in end effector output frame an defining default values for them to use them...

i need some help writing code to find the arithmetic sequences of primes. eg the arithmetic sequence of primes 7,37,67,97,127,157 differ by 30 each time, but runs out after 6 primes (187 is not prime). Is there a sequence of 7 primes? (i'm sure there is).. i want to investigate.......

Hello, I am exporting a plot (numerous plots actually) directly to eps files. In my axis labels, I have Greek and non-Greek characters. I am using the following in my plot command:

The exercise is as follows:

"Write a looping structure that finds the four substrings (of a string assigned to the nameMyString) containing only lowercase letters, uppercase letters, decimal digits, and specialcharacters."

I'm a bit lost with this one, I can find the substrings they asked for but why make it a looping structure?

If I save a worksheet after an interactive session and then return to it at a later date I have to re-execute all my commands, redefine my functions etc. but my previous plots are "kinda" remembered by Maple. For example, if I had previously executed the command
> display([p||(1..50)], insequence = true);
then that plot will be active in the sense that I can run through the 50 plots, stop at any plot, etc.
So in that sense Maple has saved the plots. But if I want...

Can you please graph this function, as well as find the domain and range in interval notation?

There is a command UsingContexts( ), however, there seems to be no list of all the available contexts or what units each of them relate to. At the moment, the only way to find the recognized contexts seems to be to go through all the units help pages one by one and look for the contexts that are mentioned. This is clearly horribly inefficient.

In addition, there seems to be no system of units readily useful for business and economics problems.

Exercise description: "Find the product of the square root of all prime numbers less than 100."

I'm very new to maple, and I'm having problems with this exercise.

I've managed to write a script that'll give me the prime numbers, but I don't know how to get the numbers into a format I can work with.

My script:

for i to 100 do

if isprime(i)=true then

print(i)

end if

This is my question that I posted at http://mathematica.stackexchange.com/questions/32338/is-there-a-triangle-like-this "I want to find the numbers $a$, $b$, $c$, $d$ of the function $y = \dfrac{a x + b}{c x + d}$ so that the triangle $ABC$ with three points  $A$, $B$, $C$  have integer coordinates and lies on the graph of the given function, then the centroid of the triangle $ABC$ (have also integer coordinates) is also lies on the graph".

How can version 17 be forced to produce [VectorCalculus]TangentLine results consistent with previous versions?

Suppose you have a 3D position vector defining a curve using a parameter t.  One can evaluate the curve at a specific value of t.  Say the point is p.  One can differentiate the curve and evaluate it at the specified value of t.  Say the result is the vector v.  Then the tangent line is p + tv.  The VectorCalculus Tangent Line...

Hello,

In multibodies system, there exists many kind of coordinates namely joint (or relative) coordinates and absolute coordinates. Moreover, for the joint (or relative) coordinates, it is possible to choose strict, simplified, or complete coordinates.

For the moment, i only find in the tutorials system modeled with complete joint (or relative) coordinates. I will give the example of a 4 bars mechanism. The kinematic scheme with this complete joint coordinates is the following :
