We describe the in-phase/quadrature covariance-matrix representation of the uncertainty in complex vectors, and transformations between this representation and the magnitude/phase and real/imaginary ...

Python's complex number objects are implemented as two distinct types when viewed from the C API: one is the Python object exposed to Python programs, and the other is a C structure which represents ...

The paper presents matrix factorization frameworks on the complex domain to get both intuitive features and high performance in image representation tasks. The real data matrix is transformed to a ...
