overridevirtual

Evaluates the covariance and gradient components This function is restricted to the monovariate case This function is limited to the only functions for which the covariance(Point-Gradient) and covariance(Gradient-Gradient) has been coded: i.e. Cubic or Gaussian, in addition to the nugget effect.

If 'flag_grad' == 0, then the output array 'covGG' is not filled.

Parameters

p1	First point of the Increment
p2	Second point of the increment
covVal	Covariance value
covGp	Covariance <G[i](x0+x,y0+y,z0+z), P(x0,y0,z0)> (dim=3)
covGG	Covariance <G[i](x0+x,y0+y,z0+z), G[j](x0,y0,z0)> (dim=3)
mode	CovCalcMode structure
flagGrad	true if the Gradient must be calculated

Remarks: : The returned arguments covVal, covGp and covGG are incremented here.; : They must have been initialized beforehand

Implements ACovGradient.
