WebDec 1, 2024 · The Gram matrix is symmetric in the case the real product is real-valued; it is Hermitian in the general, complex case by definition of an inner product. The Gram matrix is positive semidefinite, and every positive semidefinite matrix is the Gramian matrix for some set of vectors. The fact that the Gramian matrix is positive-semidefinite can be ... In the finite element method, the Gram matrix arises from approximating a function from a finite dimensional space; the Gram matrix entries are then the inner products of the basis functions of the finite dimensional subspace. In machine learning, kernel functions are often represented as Gram matrices. … See more In linear algebra, the Gram matrix (or Gramian matrix, Gramian) of a set of vectors $${\displaystyle v_{1},\dots ,v_{n}}$$ in an inner product space is the Hermitian matrix of inner products, whose entries are given by … See more The Gram determinant or Gramian is the determinant of the Gram matrix: If $${\displaystyle v_{1},\dots ,v_{n}}$$ are vectors in $${\displaystyle \mathbb {R} ^{m}}$$ then it is the square of the n-dimensional volume of the parallelotope formed by the … See more • "Gram matrix", Encyclopedia of Mathematics, EMS Press, 2001 [1994] • Volumes of parallelograms by Frank Jones See more For finite-dimensional real vectors in $${\displaystyle \mathbb {R} ^{n}}$$ with the usual Euclidean dot product, the Gram matrix is See more Positive-semidefiniteness The Gram matrix is symmetric in the case the real product is real-valued; it is Hermitian in the general, complex case by definition of an inner product.
