The LU Factorization Dashboard is a simple graphical user interface (GUI) for performing LU factorization on a matrix. Users can choose between sequential or parallel execution, provide a matrix as ...

Abstract: Sparse LU factorization is considered to be one of the most time-consuming components in circuit simulation, particularly when dealing with circuits of considerable size in the advanced ...

Abstract: With the continuous improvement of power grid stability and reliability requirements, improving the efficiency and accuracy of power system simulation has become an important research topic.

It is well known that an invertible matrix admits a factorization as a product of a lower triangular matrix L and an upper triangular matrix U if and only if all the principal minors of the matrix are ...
