#### 5.8 Method descr

call p%descr(info, [iout, root, verbosity])

This method prints a description of the preconditioner p to the standard output or to a file. It must be called after hierachy_build and smoothers_build, or build, have been called.

Arguments

info | integer, intent(out).
| Error code. If no error, 0 is returned. See Section 7 for details.
iout | integer, intent(in), optional.
| The id of the file where the preconditioner description will be printed; the default is the standard output.
root | integer, intent(in), optional.
| The id of the process where the preconditioner description will be printed; the default is psb_root_.
verbosity | integer, intent(in), optional.
| The verbosity level of the description. Default value is 0. For values higher than 0, it prints out further information, e.g., for a distributed multilevel preconditioner the size of the coarse matrices on every process.
