Massive and massless vector particles, in the framework of generalizedWeinberg-Tucker-Hammer equations, are considered in the Petiau-Duffin-Kemmerformalism. We obtain solutions of equations in the form of matrix-dyads. TheLagrangian is defined in the matrix form and the conserved electric current andthe energy-momentum tensor are obtained. The canonical quantization isperformed and the propagator of massive fields is found in the formalismconsidered.
