Logarithm of a matrix - In mathematics, the logarithm of a matrix is a generalization of the scalar logarithm to matrices. It is in some sense an inverse function of the matrix exponential.
Hessian matrix - In mathematics, the Hessian matrix is the square matrix of second partial derivatives of a scalar-valued function. Given the real-valued function
Covariance matrix - In statistics and probability theory, the covariance matrix is a matrix of covariances between elements of a vector. It is the natural generalization to higher dimensions, of the concept of the variance of a scalar-valued random variable.
Matrix subtraction - In matrix algebra, operations on matrices differ from similar operations of scalar algebra in several respects. The matrix algebra operations, in general, are not commutative and attention must be paid to whether the matrices are conformable with respect to the intended operation.
