One of the types of objects in PRAAT.
An object of type ScalarProduct represents scalar products bij between objects i and j in a metrical space.
|bij = ∑k=1..numberOfDimensions xikxjk,|
where xik and xjk are the coordinates of the k-th dimension of points i and j, respectively. From this definition one can see that scalar products, in contrast to distances, do change when the origin is shifted.
