Ephemeris.GetCovarianceData(Variable) Method

Top

Description

Gets the covariance matrix from the ephemeris at the specified vector. If any columns have a discontinuity, their after-discontinuity values will be returned. If the Ephemeris does not contain covariance data, an error is thrown.

Description:	The index within the ephemeris that specifies a vector.
Valid Range:	vectorIndex ≥ 0

Return Value

Type:

Matrix of number (size = 6 x 6)

Returns the covariance matrix from the ephemeris at the specified vector.
