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.

We consider a special class of the generalized Vandermonde matrices and obtain an LU factorization for its member by giving closed-form formulae of the entries of L and U. Moreover, we express the ...

In my Linear Algebra class we use a lot of MATLAB-- including on our timed tests and all throughout our class meetings. I want to stress to students that using professional-grade technological tools ...

Hello! I would like to know how to debug this error: "[ERROR PSM-0010] LU factorization of the G Matrix failed. SparseLU solver message: THE MATRIX IS STRUCTURALLY ...

To perform LU decomposition in Python, we can use the scipy.linalg.lu function from the SciPy library. This function returns the permutation matrix P, lower triangular matrix L, and upper triangular ...

Abstract: In this research, a new method is presented for addressing the Combined Field Integral Equation (CFIE) using the Locally Corrected Nyström (LCN) technique ...
