http://eletr.ufpr.br/edu/pds_/lab/interpreter/octave_16.html WebIn mathematics, the complex conjugate of a complex vector space is a complex vector space , which has the same elements and additive group structure as but whose scalar multiplication involves conjugation of the scalars. In other words, the scalar multiplication of satisfies. More concretely, the complex conjugate vector space is the same ... WebIn linear algebra, a Hilbert matrix, introduced by Hilbert ( 1894 ), is a square matrix with entries being the unit fractions. For example, this is the 5 × 5 Hilbert matrix: The Hilbert matrix can be regarded as derived from the integral. that is, as a Gramian matrix for powers of x. It arises in the least squares approximation of arbitrary ... raytheon executive leadership team
