Workspace Method covmat_sxExtractSqrtDiagonal

Description

Extract the square root of the diagonal of the state space covariance matrix.
This function extracts the diagonal of the state space covariance matrix
covmat_sx and computes its square root. The resulting vector can then
be used as *x_norm* argument for the OEM method to avoid scaling problems.

x_norm, covmat_sx )

Variables

GOUT	x_norm	(Vector)	The vector containing the square root of the diagonal elements of covmat_sx
IN	covmat_sx	(CovarianceMatrix)	Covariance matrix of a priori distribution This covariance matrix describes the Gaussian a priori distribution for an OEM retrieval.
