[转载]matlab中添加路径及save 、load文件方法

1 、添加存储路径:
workpath = strcat(filesep,'tmp',filesep,'example_',datestr(now,'yymmdd'),'_',datestr(now,'HHMM')); if (~isunix)
   workpath = strcat('.',workpath);
end
if (exist(workpath))
   error('The working dir already exist');
else
   mkdir(workpath);
end
SIM_DIR = workpath;

2、创建存储目录:
filename = strcat('D:存储文件夹名example.txt');
fid = fopen(filename,'at');
fprint(fid,'Length = %d  BER = %fn',BER ,SNR);
fprint(fid,'SNR Rotn');
fclose(fid);
...
fid = fopen(filename,'at');
fprint(fid,'%f %fn',SNR,Rot);
fclose(fid);

3、save和load的使用方法:
save(strcat('D:存储文件夹名',filesep,'example','.mat'),'data');
load(strcat('D:存储文件夹名',filesep,'example','.mat'));

4、批量存储.mat文件命名方法:
tempPe = Pe*100;
storageName = strcat('result_','Pe_',num2str(tempPe),'.mat');
save(storageName,'SNR','BER');
