interpolate() static void pism::io::interpolate ( const grid::DistributedGridInfo &  grid, const LocalInterpCtx &  lic, double const *  input_array, double *  output_array  ) static Bi-(or tri-)linear interpolation. This is the interpolation code itself. Note that its inputs are (essentially) the definition of the input grid the definition of the output grid input array (lic->buffer) output array (double *output_array) The output_array is expected to be big enough to contain grid.xm()*grid.ym()*length(zlevels_out)` numbers. We should be able to switch to using an external interpolation library fairly easily... Definition at line 69 of file input_helpers.cc.
