ncmovie.m

MATLAB中读写、处理科学数据文件格式NETCDF的程序

function theResult = ncmovie(theNetCDF, theMovieName, theMovieSpeed)

% ncmovie -- Play a NetCDF/Matlab movie file.
%  ncmovie('theNetCDF', 'theMovieName') opens 'theNetCDF' file
%   and plays 'theMovieName' (default = 'movie') at theMovieSpeed
%   (frames/s; default = 4).  This routine calls "movie1" to play
%   frame-by-frame.  A more sophisticated scheme would load several
%   frames at a time.
