Conditional (Density) Functions.

Parameters
alphaCoefficient vector for current grid
mgReferenz of grid pointer
malphaCoefficient vector for new grid (mg). Will be resized.
mdimMarginalize in dimension mdim
xbarPoint at which to conditionalize

Assume: mdim = 1 Compute vector with values (phi_{l1,i1}(xbar) = phi_{l1,i1}(xbar)*phi_{l2,i2}(0.5)

Compute theta = theta + alpha_{l,i}*zeta_{l,i}*int{phi_{l2, i_2}}

Generate d - 1 dimensional grid, as in marginalize

Note: Because of adaptively refined sparse grids, we cannot simply generate a regular grid. Thus, we need to add point after point to the new grid mg

Compute coefficients malpha for grid mg

Reimplemented in sgpp::datadriven::OperationDensityConditionalLinear.
