摘要
The eigenvalues of a matrix A ( lambda ), the elements of which are complex functions of a complex variable lambda , can be found with a zero finding method applied to the determinant function det A( lambda ). It is proposed to evaluate the derivatives of det( lambda ) used in the zero finding method by algorithmic differentiations. This leads to a simple and lucid algorithm. Program listings and numerical examples are given.
