Abstract: A recursive algorithm for calculating the eigenvalues of a real symmetric matrix based on LDLT decomposition is given.With this algorithm,the number of eigenvalues of a real symmetric matrix in the given interval can be counted,and the eigenvalues of the matrix can be calculated.Through theoretical analysis and numerical simulation,this algorithm is proved to be effective.
Key words: LDLT decomposition, real symmetric matrix, eigenvalue, recursive algorithm
