  We solve the time-independent Gross-Pitaevskii equation modeling the
Bose-Einstein condensate trapped in an anistropic harmonic potential using a
pseudospectral method. Numerically obtained values for an energy and a chemical
potential for the condensate with positive and negative scattering length have
been compared with those from the literature. The results show that they are in
good agreement when an atomic interaction is not too strong.
