Matter-wave solitons were constructed numerically in the context of the Bose-Einstein condensates under the Feshbach resonance management. It was observed that there was a nontrivial difference occurring for large amplitudes of the dark solitons as γ0→0. It was also observed that in contrary to what was numerically predicted, there was no threshold for the existence of dark solitons of large amplitude. It was also presented that there was no threshold on the existence of dark solitons of large amplitudes, where as such a threshold existed for bright solitons.
