The primary aim of the book is to bridge the gap between abstract mathematical theory and the "art" of computing eigenvalues for real symmetric matrices. Parlett addresses two distinct scales of the problem:
: Early chapters focus on methods where similarity transformations can be applied explicitly to the entire matrix.
Beresford Parlett's is considered the definitive authority on the numerical analysis of symmetric matrices. Since its original publication in 1980 and subsequent reprinting by the Society for Industrial and Applied Mathematics (SIAM) , it has served as a foundational text for researchers and practitioners in scientific computing and structural engineering.

: A standout feature of the book is its in-depth treatment of the Lanczos method, which at the time of writing was only beginning to be recognized for its power in solving large sparse problems.
: The book details the transformation of symmetric matrices into tridiagonal form, a critical preprocessing step for many solvers. The primary aim of the book is to
The book's influence extends beyond the classroom and into major software libraries like and EISPACK . Parlett's work laid the groundwork for modern breakthroughs, such as the MRRR algorithm (Multiple Relatively Robust Representations), developed by his student Inderjit Dhillon, which achieves

: Parlett explains how to "banish" eigenvectors once found to prevent redundant calculations during sequential computation. Impact on Numerical Linear Algebra
The text is celebrated for its "lively" commentary and expert judgments on which algorithms actually work in practice. Key technical areas include:
: Parlett provides deep insights into these iterative methods, which are the standard for computing all eigenvalues of a dense matrix.
