A Block Algorithm for Matrix 1-Norm Estimation, with an Application to 1-Norm Pseudospectra
The matrix 1-norm estimation algorithm used in LAPACK and various other software libraries and packages has proved to be a valuable tool. However, it has the limitations that it offers the user no control over the accuracy and reliability of the estimate and that it is based on level 2 …
