Input Parameters#

  • pep - the polynomial eigensolver context

  • its - iteration number

  • nconv - number of converged eigenpairs so far

  • eigr - real part of the eigenvalues

  • eigi - imaginary part of the eigenvalues

  • errest - error estimates

  • nest - number of error estimates to display

  • vf - viewer and format for monitoring

Note#

This is not called directly by users, rather one calls PEPMonitorSet(), with this function as an argument, to cause the monitor to be used during the PEP solve.
