VSM Senior Technical Editor Dr. James McCaffrey, of Microsoft Research, explains why inverting a matrix -- one of the more common tasks in data science and machine learning -- is difficult and ...

Dr. James McCaffrey from Microsoft Research presents a complete end-to-end demonstration of computing a matrix inverse using the Newton iteration algorithm. Compared to other algorithms, Newton ...

The inverse is often of interest, and a method is developed to find its components in close form when the T × T matrix has only 2m + 1 nonvanishing (central) diagonals $ (1 \leqq m < T)$. The method ...
