Hey,

I'd like to be able to give a program a directory, and then have it run a second program on all files in that directory. For example, say I have a function, myFun(filePath) that reads, processes, and displays data from the file specified by filePath. Now, I'd like to write another function, in pseudocode below:

funtion dirFun(dirPath)

f = files(dirPath);

for x = 1:length(files);

myFun(f[x]);

end

Something like this. I want a function, here "files" which will return all of the file names within the directory, so that I can run the program on all my files. Is there such a function in MATLAB?

在 MATLAB Online 中打开

The function is dir().

Files=dir('*.*');
for k=1:length(Files)
   FileNames=Files(k).name
end

@Amin S: no need for a loop:

S = dir(...); % all of the names are in the structure S anyway.
N = {S.name}; % but if you really want a cell array of names, do this.

@Vidz

What leads you to expect that nearly 11 years ago, @Clement Wong happened to need to start from the third entry instead of the first?

I suspect that you are thinking that the first entry is "." and the second entry is ".." but if so then that is an incorrect assumption on every operating system that MATLAB has ever been supported on. If you want to filter out "." and ".." you should do so by name, not by assuming they are in a particular position.
