Distribution objects

Description

• 

The IsSubspace method decides whether Distribution object dist1 specifies a subspace of tangent space which is contained in the subspace specified by Distribution dist2 at each point in space. It returns the values true or false.

• 

This method is associated with the Distribution object. For more detail see Overview of the Distribution object.
