Matrix decomposition and application
 
Abstract    This paper focuses on the matrix QR decomposition, singular value decomposition and LU decomposition and their applications, and were calculated with examples, selected a number of practical examples to learn more about the application of matrix decomposition. In some computer programs can deal with problem areas, joined the MATLAB software, the calculation process, which gives us more quickly to solve complex computing problems.
Keywords  QR decomposition, singular value decomposition, LU decomposition
