Abstract: We propose a method to search the inverse matrix for a type of special multiplied triangular matrix quickly. The proposed method can be used for the decomposition of Diagonal matrix, Lower ...

Abstract: A new analytical method of constructing the inverse matrix to the check matrix of the system of embedded inner codes for the generalized error-locating codes is proposed.

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 ...

Dozens of machine learning algorithms require computing the inverse of a matrix. Computing a matrix inverse is conceptually easy, but implementation is one of the most challenging tasks in numerical ...

If the entries on the main diagonal of a upper or lower triangular matrix are all 1, the matrix is called upper or lower unitriangular. Strictly triangular matrix: If all of the entries on the main ...
