Abstract:
The secular equation with real symmetric positive definite n×n matrix is transformed into a system of n2 quadratic equations for which it is possible to construct a convergent procedure realizing an iterative solution. An example of the numerical realization of the method for solving the problem of determining the electronic energy spectrum is given.
