WitrynaEigenvalues are associated with the linear equation system as the special scalars set. It has its general use in the area of matrix equations. We can also call it characteristic … WitrynaBoettcher [2] by means of the WKB method and numerical integration. In fact, Bender and Boettcher [2, 4] discussed the calculation of the eigenvalues by means of the DM (see also [7]). They concluded that the method is only useful when 1<4 and that the convergence to the exact eigenvalues is slow and not monotonic because the …
