QR Decomposition of Matrix and Program Design
Abstract:The matrix is a important tool in class of mathematical research, and it has a very wide range of applications, matrix decomposition plays a key role in matrix theory and development of modern computational mathematics. QR decomposition of the matrix can be used Householder matrix transformations, Gram-Schmidet orthogonalization, Givens transformation matrix method. This paper presents several important and proven method, and gives specific algorithm design, in order to implement complex high-end computer matrix QR decomposition.
Key words:QR decomposition; Algorithm design; Householder transformation
