A square matrix of order n has at most n eigenvalues. An identity matrix has only one eigenvalue which is 1. The eigenvalues of triangular matrices and diagonal matrices are nothing but the elements of their principal diagonal. The sum of eigenvalues of matrix A is equal to the sum of ...
Let A be a 2 cross 2 matrix, such that the columns are unitary vectors and orthogonal. Prove that A is invertible and that A^{-1} = A^{T} Calculate the dot product of vectors A = 2 1 and B = 3 2 . The three vectors u = u_x i + 3j + 2k, v = -3i + v_y j + 3k...
Let A be a matrix in M(n,C) and {λ1, λ2, ···, λn} the set of eigenvalues (containing multiplicities) of A. Then 3the exponential e −itA is given by the clear formula e −itA =...K. Fujii and H. Oike : How to Calculate the Exponential of Matrices, quant-ph/...

You have a 4 x 4 matrix. The eigenvalues are going to be the roots of a polynomial of degree 4. Degree 4 is exactly solvable. But the solution is going to be long. You can simplify() with 'steps', 25 to get a more compact form. For example ThemeCopy (2^(2/3)*3^(1/2)*(...
where n runs from 0 to infinity, meaning the full matrix is infinite-dimensional. My Questions: 1- How can I define this density matrix in Mathematica? 2- Is there a more efficient way to represent it symbolically? 3-What is the best approach to compute its eigenvalues numerically?
If matrix a^2 = a, what is a? Compute the matrix \begin{bmatrix} 3\\ 2\\ 5 \end{bmatrix}\begin{bmatrix} 2 &-5 &3 \end{bmatrix}. How do eigenvalues of a matrix relate to eigenvalues of the square of the matrix? Explain the Row matrix along with an example. ...

I need to find all the eigenvalues of a large matrix which is 10000X10000, and I have to loop it for some 1000 times.My computer has sufficient memory, the problem is it's taking too much time. It is taking 1min or so to calculate the eigenvalues...
