Abstract
The matrix joint diagonalization is a fundamental notion for studying the blind signal processing and the independent component analysis. We reformulate some classical results on the topic in terms of shear matrices. These matrices appear naturally in differential geometry and group theory and the present paper deals with certain perturbations of joint diagonalizers for which the knowledge of shear matrices is crucial.File in questo prodotto:
