For example: x = [1+j; 1-j; 2-j; 1+2j] % random complex matrix. x =. 1.0000 + 1.0000i. 1.0000 - 1.0000i. If you have access to Matlab or Octave, then producing such matrices is as easy as issuing the following commands: n = 10; A = rand (n) + 1i*rand (n); [U,~] = qr (A); I recommend that you use software such as this to generate these matrices in general.Before running any of these examples, you will need to generate the following positive definite and indefinite Hermitian matrices: A = full (delsq (numgrid ('L', 10))); B = gallery ('uniformdata',10,0); M = [eye (10) B; B' zeros (10)]; The structure of M here is very common in optimization and fluid-flow problems, and M is in fact indefinite.A square matrix, A, is Hermitian if it is equal to its complex conjugate transpose, A = A'. In terms of the matrix elements, this means that a i, j = a ¯ j, i . The entries on the diagonal of a Hermitian matrix are always real. Since real matrices are unaffected by complex conjugation, a real matrix that is symmetric is also Hermitian. Lets suppose I have a (n x n) hermitian matrix A, defined as a product of (n x m) matrix B and it's hermitian transpose: A = B*B' Matrix B is known, it is not structured and is positive definite. 1) How do I decompose matrix A as a product of u*u', where u is a vector of length n? 2) Is it possible to calculate u directly from B, without first ...Seems complicated? Once again Matlab has a fast way of accomplishing the same task. The eig() command nds the eigenvalues and eigenvectors of a matrix directly. The output is given in two matrices. The rst is a matrix whose columns contain the eigenvectors while the second is a diagonal matrix containing the eigenvalues. > [V,E] = eig(A) V =that is Hermitian: its conjugate transpose (which in this case is the transpose, because the matrix is real) is itself. As for ( 2 0 − 2 0 0 0 − 2 0 2), that is the "classical adjoint" or adjugate. It has nothing to do with the Hermitian adjoint or conjugate transpose. The terminology is unfortunately confusing.
