WebMatrix and Gram determinant. Let in the Euclidean space the scalar product is defined in a known manner . Gram matrix of a vectors system is called a square matrix consisting of various scalar products of these vectors: The Gram matrix is a symmetric matrix. Its determinant is called the Gram determinant (or Gramian ) of a vector system : P. WebFeb 9, 2024 · It’s now easy to see that in Property 5, the Gram determinant is 0 if the xi x i ’s are linearly dependent, and attains its maximum if the xi x i ’s are pairwise orthogonal (a quick proof: in the above matrix, rij = 0 r i j = 0 if i≠j i ≠ j ), which corresponds exactly to the square of the volume of the hyperparallelepiped spanned by the xi x i ’s. WebJacobian matrix and determinant.
