We characterize real functions $f$ on an interval $(-\alpha,\alpha)$ for
which the entrywise matrix function $[a_{ij}] \mapsto [f(a_{ij})]$ is positive,
monotone and convex, respectively, in the positive semidefiniteness order.
Fractional power functions are exemplified and related weak majorizations are
shown.
