Bathymetric Data Fitting based on Fourier Series of Linear Complementarity

Fourier series of Linear Complementarity is introduced into the field of bathymetric data fitting. Firstly, in data preprocessing, the principles of grid processing in bathymetry is given in the paper. And then, different methods of complementarity (none complementarity, direct complementarity and linear complementarity) are compared and analyzed, which shows that the Fourier Series of linear complementarity method can effectively improve the convergence speed of modeling. And the result futher illustrated that the Fourier series of linear complementarity has a wide application in the bathymetric data processing.
