Question

I start with Matlab and would like to know how could I access to a folder and get contents to access files and read them.
I have a variable in workspace tmpfolder that is equal to ‘path to folder’ but I don’t find how could I make dir(tmpfolder) and get files, browse any file content to get a string value…

If you have an image file in jpeg format in another folder named myimage and a text file called mytext, use:

prefix_image='myimage';
prefix_data='mytext';
fileformat='.jpg';
dataformat='.txt';
folder='C:\Users\khaled\Documents\MATLAB\';

image = imread(strcat(folder,prefix_image,fileformat));

data=textread(strcat(folder,prefix_data,fileformat),'%f');
