For large discrete series representations of SU(3,1), we give expressions of the radial parts of their matrix coefficients in terms of the generalized hypergeometric series, and describe their asymptotic behavior, explicitly. Geometrically speaking, this is to obtain an explicit formula for some Hilbert space of non-holomorphic harmonic L2-sections in an SU(3,1)-equivariant vector bundle.

Keywords: Matrix coefficients, discrete series.
