Carl D. Meyer is a highly regarded mathematician known for his contributions to linear algebra, numerical analysis, and matrix theory. Some of his notable contributions include:


 * 1) Matrix Analysis and Applied Linear Algebra: Meyer authored the widely used textbook "Matrix Analysis and Applied Linear Algebra," first published in 2000 by SIAM and the second edition published by SIAM in 2023. These books are renowned for their clear explanations and comprehensive coverage of topics in linear algebra, including matrix theory, eigenvalues, eigenvectors, and applications in various fields.
 * 2) Nonnegative Matrices and Perron-Frobenius Theory: Meyer has made significant contributions to the study of nonnegative matrices and the Perron-Frobenius theory, which deals with the spectral properties of nonnegative matrices. Through his development of the concepts of stochastic complementation and its extension to Perron complementation his work has helped advance understanding in theoretical linear algebra along with applications in diverse fields such as biology, economics, and computer science.
 * 3) Numerical Analysis: Meyer has also contributed to numerical analysis, particularly in the development of algorithms for solving problems related to eigenvalues and singular values of matrices as well as solving  large systems of linear equations. His research in these areas have had practical applications in scientific computing and engineering.

Overall, Carl D. Meyer is a fellow of The Society for Industrial and Applied Mathematics, and he is recognized as a leading authority in linear algebra and matrix theory. His work has had a profound effect on both theoretical developments and practical applications in mathematics and other disciplines.
