pyPDAF.PDAF.diag_rmsd

pyPDAF.PDAF.diag_rmsd(dim_p: int, statea_p: np.ndarray, stateb_p: np.ndarray, comm_filter: int) → Tuple[float, int]

Compute the root mean squared distance between two vectors.

Parameters:

• dim_p (int) – state dimension

• statea_p (ndarray[np.float64, ndim=1]) – State vector A Array shape: (dim_p)

• stateb_p (ndarray[np.float64, ndim=1]) – State vector B Array shape: (dim_p)

• comm_filter (int) – Filter communicator

Returns:

• rmsd_g (double) – Global RSMD

• status (int) – Status flag (0=success)
