摘要：
We consider some approximation problems in the linear space of complex matrices with respect to unitarily invariant norms. We deal with special cases of approximation of a matrix by zero-trace matrices. Moreover, some characterizations of zero-trace matrices are given by means of matrix approximation problems.
