Gram Matrix
Given 
points with 
-D vector coordinates 
, let 
be the 
matrix whose 
th columnconsists of the coordinates of the vector 
, with 
, ..., . Then define the 
Gram matrix of dot products 
as
where
denotes the Transpose. The Gram matrix determines the vectors up to Isometry.- Isoperimetric Quotient
