Matlab--保存数据，且文件以时间命名

save (FunctionNowFilename('test', '.mat' ));

 

%----------------------filename: FunctionNowFilename.m -----------------------

function [ fname ] = FunctionNowFilename( pre, post )
%NOW_FILENAME convert current time to filename
% NOW_FILENAME returns current time to filename as:
