WebFeb 12, 2024 · I am trying to solve the following eigenvalue problem: with BCs . (z) is a vector with size ( ,1), is the eigenvalue, and is the eigenvector. I am attempting to find for the lowest mode (i.e. solution with ) and the corresponding using the following code: Theme. Copy. Amatrix = zeros (nz-1,nz-1); Coeff = zeros (nz,1); Web2 Eigenvalues are ordered by their magnitude in general. If you want to preserve the order all over the region, the only way (as much I know) is to try to get an analytical expression. For example consider this simple matrix H [x_, y_] = { {0, Cos [x] + Cos [y]}, {Cos [x] + Cos [y], 0}} If I go with analytical expression
