Complex matrix algebra is of great importance to a wide variety of applications. One of the most important application areas is telecommunications. Matrix calculations are used in communications ...

Abstract: This paper presents matrix inversion algorithms based on LU decomposition and QR decomposition and LDLT decomposition (i.e. improved Cholesky decomposition) and the time complexity of the ...

Abstract: This paper describes a special-purpose matrix inversion technique developed in the System-Planning Branch of TVA (Tennessee Valley Authority). This is the first known use of the method. It ...
