= PDAF_diag_ensmean = 

This page documents the routine `PDAF_diag_ensmean` of PDAF, which was introduced with PDAF V3.0.

This routine computes the ensemble mean state vector.

The routine can be called in the pre/poststep routine of PDAF both before and after the analysis step to compute the ensemble statistics.

The interface is the following: 
{{{
SUBROUTINE PDAF_diag_ensmean(dim, dim_ens, state, ens, status)
}}}
with the following arguments:
{{{
  INTEGER, INTENT(in) :: dim               ! state dimension
  INTEGER, INTENT(in) :: dim_ens           ! Ensemble size
  REAL, INTENT(inout) :: state(dim)        ! ensemble mean state vector
  REAL, INTENT(in)    :: ens(dim, dim_ens) ! State ensemble
  INTEGER, INTENT(out) :: status           ! Status flag (0=success)
}}}
