Hi!

I am comptuing the eigenvalues and the characteristic polynomial of a 8 by 8 symmetric matrix, say M. Thus, we define the matrix M, and compute its charast. plynm. by

 

 

and its eigenvalues with the command

 

 

Well, Maple returns the charast. polynm. an dthe eigenvalues. But, if we compute p(E[k]), for k=1,...,8, thats is, the values of the polynomial p(x) in the eingenvalues, Maple not turns cero!!! I'm really confused ... anyone know what could be happening?

 

Maple attached file with this example. Thank very much for your help!!

hi...amount of Determinant  is infinity?how i can remove this bad calculation ?

how to get maple to do linear algebra in Z_2 (integers modulo 2)

I don't want it to solve and then reduce mod 2 I want it to work over Z_2 so basis([ [1,1,1], [1,-1,1 ]) = [1,1,1]  etc


Hello Everyone

 

I am new to Maple and I have to find the determinant of the following matrix

 

Matrix comprising of Bessel Functions whose determinant is to be calculated

Here k is a constant.

 

Can you please help me with it.

 

Thanks in advance.

Hi,

When I calculate the nullspace of a Matrix my solution comes out in a different order than Maple.  So, the question is what steps does Maple use to calculate Nullspace, ColumnSpace, and eigenvalues.  All of these are calculated by Maple in a different order that when I calculate by hand.

What I meant to say is that the answer given by for nullspace is in a different order than if I were do the same calculation by Hand.   

A=<<[1,1,1,1],[1,2,3,4],[4,3,2,1]>>   this is what got calculating the Nullspace by hand <1,-2,1,0>,<2,-3,0,1>  when Maple does the calc. It returns the answer in the opposite order

 

Thanks

Bill

Is there a way to do the following on Maple:

I want Maple to use Jacobi's method to give an approximation of the solution to the following linear system, with a tolerance of 10^(-2) and with a maximum iteration count of 300.

 

The linear system is

x_1-2x_3=0.2

-0.5x_1+x_2-0.25x_3=-1.425

x_1-0.5x_2+x_3=2

 

Thanks.

Exercise Prove that (-1)u = - u in any vector space. Note that (-1)u means the number -1 is multiplied to the vector u, and - u means the negative vector in the fourth property of the definition of vector spaces.

Answer

Exercise Prove that (a1u1 + a2u2) + (b1u1 + b2u2) = (a1 + b1)u1 + (a2 + b2)u2 in any vector space.

Answer

Exercise Give a detailed reason why, in any vector space,

  • u + v = 0 ⇒ u = - v.

  • 3u + 2v - 4w = 0 ⇒ v = - 3/2 u + 2w.

I wrote down a proceduer in maple for solving integro diff. equations which result in an ill conditioned linear system of algebraic equations. I used the LinearSolve command with method=LU to solve the system but my algorithm failed, and does not converge. Is there any command in maple for solving such systems

let A be a matrix=

 

[  7        7      9    -17

   6        6      1    -2

 -12    -12    -27    1

   7       7      17   -15 ]

What is the reduced row echelon form of A?

What is the rank of A?

A consistent system of linear equations in 14 unknowns is reduced to row echelon form. There are then 10 non-zero rows (i.e. 10 pivots). How many parameters (free variables) will occur in the solution?

hi fellas
i have questions which maybe very common but i can't handle it right now
there are 9 matrices. each one of them is a 3*3 matrix, not to say all the matrices' elements are in symbolic form.
all i want is to form a matrix made out of the 9 matrices i mentioned above in **maple**; i mean something like "cell" in MatlabI'll be appreciated for your help

how to calculate the first step

(2,0) -> (1,1,1) and (1,4) -> (1,2,0)

how to use maple command to get (1,1,1) and (1,2,0)

how to use maple command to calculate rep(h)

 

to get (0,-1/2,1) and (1,-1,0)

So im trying to write a maple script that computes the Jordan form of a given (3x3)- matrix
A. If {a,b,c} is a basis with respect to which A is in Jordan form, then I'm trying to make it
plot the three lines spanned by a, b and c, in the standard coordinate system. I was hinted to use plot3d here.

sidenote: I know how to compute the jordan matrix of A, such by find the eigen vectors and generalised eigen vectors and putting them in as columns in a 3x3 matrix say S,   where S is invertible    then  (S^-1)*(A)*(S) = (J).

Thanks in advance. <3

In my research a I need to solve the linear equation (getting its null space) under some constraints.

The matrix is given below:

 

The constraints shall be (x[1]...x[16]>0, x[17]...x[20] arbitary...)

The solutions shall actually be a canonical combination of a lot of vectors, (canonical combination means possitive sums of vectors). And I wish to get those vectors. is there a way that I could achieve this by Maple?
