How do you prove that $tr(B^{T} A )$ is a inner product?
In linear algebra, the trace of a square matrix A, denoted tr(A), is defined to be the sum of elements on the main diagonal (from the upper left to the lower right) of A. The trace is only defined for a square matrix (n × n). It can be proved that the trace of a matrix is the sum of its (complex) eigenvalues (counted with … See more The trace of an n × n square matrix A is defined as Expressions like tr(exp(A)), where A is a square matrix, occur so often in some fields (e.g. multivariate statistical theory), that a shorthand … See more If A is a linear operator represented by a square matrix with real or complex entries and if λ1, ..., λn are the eigenvalues of A (listed according to their algebraic multiplicities), … See more Stochastic estimator The trace can be estimated unbiasedly by "Hutchinson's trick": Given any matrix $${\displaystyle W\in \mathbb {R} ^{n\times n}}$$, and any random $${\displaystyle u\in \mathbb {R} ^{n}}$$ See more Let A be a matrix, with Then See more Basic properties The trace is a linear mapping. That is, A matrix and its transpose have the same trace: See more In general, given some linear map f : V → V (where V is a finite-dimensional vector space), we can define the trace of this map by considering … See more If a 2 x 2 real matrix has zero trace, its square is a diagonal matrix.
