The Characteristic Polynomials for a Class of Eigenvalue Problems
Joseph Chawki Hassab · IEEE Transactions on Computers · 1974
Characteristic polynomials are here generated for a class of eigenvalue problems using the singularity condition previously encountered in the solution of corresponding forced system. The process is efficient and requires n2/2 operations in contrast to n3 operations required by techniques such as the Leverrier-Faddeev method.
