Calculate the covariance between variable (Z) and a gradient component (Gi)

Parameters

jvar0 for the variable (Z); idim=ivar-1 for the gradient G_idim
p1First point
p2Second point
modeCovCalcMode structure
Returns

bool  flagGrad = false 
) const
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
p1First point of the Increment
p2Second point of the increment
covValCovariance value
covGpCovariance <G[i](x0+x,y0+y,z0+z), P(x0,y0,z0)> (dim=3)
covGGCovariance <G[i](x0+x,y0+y,z0+z), G[j](x0,y0,z0)> (dim=3)
modeCovCalcMode structure
flagGradtrue if the Gradient must be calculated
Remarks
: The returned arguments covVal, covGp and covGG are incremented here.
: They must have been initialized beforehand
