MS9
Matrix Functions

3:00 PM-5:00 PM
Room: Ballroom 2

Functions of matrices arise in many areas of scientific computation. The exponential is intimately associated with the solution of differential equations and the logarithm arises in corresponding inverse problems. The square root of a matrix is a useful theoretical tool and needs to be computed in some applications. The speakers in this minisymposium will describe recent progress on the theory of matrix functions and on their numerical computation. They will give an overview of recent progress in the theory and computation of matrix functions. They will not assume prior knowledge of research in this area.
