Abstract Let A be an n × n Hermitian matrix and A = UΛUH be its spectral decomposition, where U is a unitary matrix of order n and Λ is a diagonal matrix. In this note we present the perturbation ...

Sometimes, you may want to process or step over errors. To do this, put all the code into modules and push a code to abort if the error count goes above some maximum ...
