Hello,

I have a little question concerning the definition of the rotation matrix in the rigid body frame.

The rotation matrix is defined like that in the help menu : "The rotation matrix that transforms a vector expressed in the outboard frame to the inboard frame".

Consequently, we have :

Hello,

I would like to define my model with symbolic parameters. Consequently, i have to define the symbolic parameters and theirs values in main folder.

To illustrate, i define my parameters a1, a2 like this.

After, i need to define a frame by using the parameter a1. This frame is define like this :

Solve the system of equations:

Good afternoon Professor.

Is there any direct approach like Jacobi,Gauss-seidel, & SOR methods in Maple to solve a given linear system of equations by using Conjugate gradient method & Preconditioned Conjugate method.

I request you to help me out to generate Maple commands to solve.

If are the roots of the equations .
Prove that min

When executing "P, k := LyapunovSolve(A, C)" command, I got the following warning: 

"Warning, Matrices have common or very close eigenvalues; perturbed values were used to solve the equation"

Although Maple can give the solution, P and k don't satisfy the equation: 

A.P+P.A^%T-C = 0        (1)

Are there any other ways to solve the Lyapunov equation (1)?

Using ScientificConstants[GetElement] I'm supposed to get all the element constants, but I don't see the molar mass and have trouble believing that it isn't defined.

Question how do I get the molar mass of an element?

Hi everyone. Someone should pls. teach me how to plot a graph in maple. i've never done this before and I hope what I'm about to do is very much feasible. I don't have a function to plot, I'm plotting the errors from my computation against time(t) at interval 0 t 1. Someone shoukd pls. explain this for me with random values or use the sample values below .

  time           error1         error2

Good morning Professor.

I request you to help me out to create an Augmented Matrix of a given system of linear equations with more number of variables.

With thanks & regards.

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:

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.......
