Best Answer

clc ; clear all ;
data = importdata('nc.txt') ;
lon = data(:,1) ; 
lat = data(:,2) ;
ncfile = 'myncfile.nc' ;
% Longitude 
nccreate(ncfile,'lon','Dimensions',{'lon',1,length(lon)},'DeflateLevel',5) ;
ncwrite(ncfile,'lon',lon) ;
ncwriteatt(ncfile,'lon','long_name','longitude');
ncwriteatt(ncfile,'lon','units','degrees');
% Latitude 
nccreate(ncfile,'lat','Dimensions',{'lat', 1, length(lat)},'DeflateLevel',5) ;
ncwrite(ncfile,'lat',lat)
ncwriteatt(ncfile,'lat','long_name','latitude');
ncwriteatt(ncfile,'lat','units','degrees');
