In the case of a real matrix , equation ( 1) reduces to (2) where denotes the transpose. Positive definite matrices are of both theoretical and computational importance in a wide variety of applications.
SpletTensors can then be defined as sets of real numbers that transform in a particular way under this change in coordinate system. For example. · A tensor of zeroth rank is a scalar that is independent of the coordinate system. · A covariant tensor of rank 1 is a vector that transforms as v ′ i = ∂ xj ∂ x ivj.
