MATLAB中读写、处理科学数据文件格式NETCDF的程序

function theResult = gt(self, other)

% ncvar/gt -- Redirection operator.
%  gt(self, theNetcdf) redirects self, an ncvar object,
%   into theNetcdf, a netcdf object.  This copies the
%   variable definition, but not its data or attributes.
%  gt(self, theNCVar) redirects the contents of self, an
%   ncvar object, into theNCVar, an ncvar object.  This
%   copies variable data, but not the attributes.
%  gt(self, theNCVar) redirects the contents of self, a
%   double or char object, into theNCVar, an ncvar object.
