Constructor Detail

CovarianceMatrix

public CovarianceMatrix(AbsoluteDate epoch,
                        LOFType lofType,
                        Frame frame,
                        RealMatrix lastMatrix)

Covariance Matrix constructor.

Parameters:

epoch - the epoch

lofType - coordinate system for covariance matrix, for Local Orbital Frames

frame - coordinate system for covariance matrix, for absolute frames

lastMatrix - the covariance matrix

Method Detail

getMatrix

public RealMatrix getMatrix()

Get the covariance matrix.

Returns:

the covariance matrix

getEpoch

public AbsoluteDate getEpoch()

Get the epoch relative to the covariance matrix.

Returns:

the epoch

getLofType

public LOFType getLofType()

Get coordinate system for covariance matrix, for Local Orbital Frames.

The value returned is null if the covariance matrix is given in an absolute frame rather than a Local Orbital Frame. In this case, the method getFrame() must be used instead.

Returns:

the coordinate system for covariance matrix, or null if the covariance matrix is given in an absolute frame rather than a Local Orbital Frame

getFrame

public Frame getFrame()

Get coordinate system for covariance matrix, for absolute frames.

The value returned is null if the covariance matrix is given in a Local Orbital Frame rather than an absolute frame. In this case, the method getLofType() must be used instead.

Returns:

the coordinate system for covariance matrix
