◆ IL_init_func_2d()

void IL_init_func_2d ( struct interp_params params,
grid_calc_fn grid_f,
matrix_create_fn matr_f,
check_points_fn point_f,
secpar_fn secp_f,
interp_fn interp_f,
interpder_fn interpder_f,
wr_temp_fn temp_f 

Initializes functions used by the library

grid_fcalculates grid for given segment
matr_fcreates matrix for a given segment
point_fchecks interpolation function at points
secp_fcalculates aspect, slope, curvature
interp_fradial basis function
interpder_fderivatives of radial basis function
temp_fwrites temp files
