DistanceFunction is an option for functions such as Nearest that specifies the distance value to assume between any two specified points.
DistributedContexts is an option for various parallel computing functions that specifies which definitions for symbols appearing in an expression should be distributed to all ...
DistributeDefinitions[s_1, s_2, ...] distributes all definitions for the symbols s_i to all parallel kernels.DistributeDefinitions["context"] distributes definitions for all ...
Distributed[x, dist] or x \[Distributed] dist asserts that the random variable x is distributed according to the probability distribution dist.Distributed[{x_1, x_2, ...}, ...
DistributionFitTest[data] tests whether data is normally distributed. DistributionFitTest[data, dist] tests whether data is distributed according to dist. ...
DistributionParameterQ[dist] yields True if dist is a valid distribution, and yields False otherwise.
Dithering is an option for ColorQuantize that specifies whether or not to apply dithering while quantizing the pixel values.
Divide
