Abstract Linear Algebra 16 | Gramian Matrix
Orthogonal projection onto a finite-dimensional subspace can be computed by turning the “find the right coefficients” problem into a linear system...
Hilbert Spaces 4 | Parallelogram Law
The parallelogram law links geometry to algebra: in any inner product space, the squared lengths of the sum and difference of two vectors always...
Abstract Linear Algebra 20 | Gram-Schmidt Orthonormalization
Gram–Schmidt orthonormalization turns any basis of a finite-dimensional inner-product subspace into an orthonormal basis that fits the geometry of...
Functional Analysis 11 | Orthogonality [dark version]
Orthogonality in an inner product space is defined entirely through the inner product: two vectors are orthogonal exactly when their inner product is...
Abstract Linear Algebra 16 | Gramian Matrix [dark version]
Orthogonal projection onto a finite-dimensional subspace can be computed by solving a linear system built from inner products—using a special matrix...
Hilbert Spaces 12 | Bessel's Inequality
Bessel’s inequality links the “energy” of any vector to its coordinates along an orthonormal system, guaranteeing that the total squared...
