griddata_nearest

PURPOSE ^

GRIDDATA_NEAREST - returns interpolated u_m function of x_m and y_m on a grid

SYNOPSIS ^

function [u]=griddata_nearest(x_m,y_m,u_m,x,y)

DESCRIPTION ^

GRIDDATA_NEAREST - returns interpolated u_m function of x_m and y_m  on a grid

   This function returns interpolated u_m function of x_m and y_m,
   on the grid defined by x and y.
   See griddata_nearest_matrix for the case where x_m,y_m and u_m are matrices 
   and x,y are vectores.
   See griddata_perso for a user defined version of griddata ( with fuzz coeff).

   Usage:
      [u]=griddata_nearest(x_m,y_m,u_m,x,y)
