Matrix classes for matrices that are block-tridiagonal and sparse, and simply "block sparse". These talk together, and furthermore containts an algorithm for inversion of the block-tridiagonal version ...

Solution of the Schodinger Eqation for Harmonic Oscillator Confined in Potential well (Dirichlet's Condition on both boundaries). Shifted Inverse Power routine is used to find eigen values Tridiagonal ...

Abstract: The solution of tridiagonal linear systems is used in in various fields and plays a crucial role in numerical simulations. However, there is few efficient solver for tridiagonal linear ...

Abstract: Computing three-phase short-circuit currents (3pSCCs) in large-scale high-voltage power systems needs to find the inverted nodal admittance matrix, which is generally time- consuming.

This study presents recursive relations on the permanents of k – tridiagonal Toeplitz matrices which are obtained by the reduction of the matrices to the other matrices whose permanents are easily ...
