Solve the system of equations:

Good afternoon Professor.

I am M.Anand working for SRIIT, as Assistant Professor in Mathematics in Hyderabad, INDIA.

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:

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:

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...
