The Gross-Pitaevskii equation, which describes the dynamics of a one-dimensional uniformly feeded attractive Bose-Einstein condensate in an expulsive potential of arbitrary harmonic shape -a{sub 2}x{sup 2}+a{sub 1}x, is solved analytically following the inverse scattering transform method. Within this approach, bright-matter waves are obtained as exact envelope-soliton solutions of the nonlinear Schroedinger equation with a complex harmonic potential. The envelope shapes mimic double-lump pulses of unequal amplitudes symmetric with respect to the potential maximum, moving simultaneously at nonconstant accelerations with amplitudes that vary in time.
