Subroutine descr

call p%descr(info, [iout])

This routine 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 8 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.

For compatibility with the previous versions of MLD2P4, this routine can be also invoked as follows:

call mld_precdescr(p,info [,iout])
