MATLAB中读写、处理科学数据文件格式NETCDF的程序

function theResult = ncload(theNetCDFFile, varargin)

% ncload -- Load NetCDF variables.
%  ncload('theNetCDFFile', 'var1', 'var2', ...) loads the
%   given variables of 'theNetCDFFile' into the Matlab
%   workspace of the "caller" of this routine.  If no names
%   are given, all variables are loaded.  The names of the
%   loaded variables are returned or assigned to "ans".
%   No attributes are loaded.
