这个例子展示了如何在%部署模式下对数据文件使用% "load/save"函数。本例中有三个源数据文件%。% user_data。用户数据\extra_data。Mat % ..\externdata\extern_data. txt使用mcc命令编译这个例子:% mcc -m ex_loadsave。M -a 'user_data。Mat ' -a % '.\userdata\extra_data. txtMat“% -a”..\externdata\extern_data.”当前MATLAB主文件目录下的所有文件夹将被包含为ctfroot的相对路径;所有其他文件夹的%文件夹%结构都包含在%磁盘驱动器根目录下的可部署归档文件中。 % % If a data file is outside of the main MATLAB file path, % the absolute path will be % included in deployable archive and extracted under ctfroot. For example: % Data file % "c:\$matlabroot\examples\externdata\extern_data.mat" % will be added into deployable archive and extracted to % "$ctfroot\$matlabroot\examples\externdata\extern_data.mat". % % All mat/data files are unchanged after mcc runs. There is % no encryption on these user included data files. They are % included in the deployable archive. % % The target data file is: % .\output\saved_data.mat % When writing the file to local disk, do not save any files % under ctfroot since it may be refreshed and deleted % when the application isnext started. %==== load data file ============================= if isdeployed % In deployed mode, all file under CTFRoot in the path are loaded % by full path name or relative to $ctfroot. % LOADFILENAME1=which(fullfile(ctfroot,mfilename,'user_data.mat')); % LOADFILENAME2=which(fullfile(ctfroot,'userdata','extra_data.mat')); LOADFILENAME1=which(fullfile('user_data.mat')); LOADFILENAME2=which(fullfile('extra_data.mat')); % For external data file, full path will be added into deployable archive; % you don't need specify the full path to find the file.
