摘要

We present an algorithm that can find all the eigenvalues of an n × n symmetric Pascal matrices in O(n2log n) operations. We take advantage of real symmetry and the Pascal structure. Our scheme consists of an O(n2log n) Lanczos tridiagonalization procedure and an O(n) QR diagonalization method and the Fast Fourier Transform (FFT).
