We present a solution of M(atrix) theory describing type IIA fundamental
string. Our construction is based on the central charge of the longitudinal
membrane (= fundamental string), the BPS saturation condition and the relation
between M(atrix) theory and supersymmetric Yang-Mills theory. The fundamental
string corresponds to a photon in supersymmetric Yang-Mills theory.Comment: 11 pages + 2 uuencoded eps figures, LaTeX, errors corrected and
