Matrix inequalities and means constitute a vibrant area of contemporary mathematical research, blending classical matrix theory with modern applications in numerical analysis, control theory and ...
In this paper, we present new error bounds for the Lanczos method and the shift-and-invert Lanczos method for computing e -Ï„A v for a large sparse symmetric positive ...
For a (row) diagonally dominant matrix, if all of its off-diagonal entries and its diagonally dominant parts (which are defined for each row as the absolute value of the diagonal entry subtracted by ...
