How do I read all the files in a folder in MATLAB? Question. 17 answers. Asked 11th Jan, 2014; Vinod Kumar; I have a folder that contains around 400 color images, all of which need to be read for. Then you can use BufferedReader to read line by line, Scanner to read using different delimiters, StreamTokenizer to read a file into tokens, DataInputStream to read binary data and primitive data types, SequenceInput Stream to link multiple files into one stream, FileChannel to read faster from large files, etc Java Class Path MATLAB maintains a path for Java classes separate from the search path. That means even if you have a .class or .jar file on the MATLAB path, unless you use javaaddpath you will not be able to use it. To see what is currently on the path use javaclasspath. Running this command you will show you a long list of files that ship. The above function will return a file name with its extension. It returns the rightmost characters of a string up to, but not including the rightmost '\'. You can call this function as: It returns the rightmost characters of a string up to, but not including the rightmost '\' Arguments con.
