FTP class -

Connect to FTP server

Description

Connect to an FTP server by calling the ftp function, which creates an FTP object. Perform file operations using methods on the FTP object, such as mput and mget. When you finish accessing the server, call the close method to close the connection.

Construction

f = ftp(host,username,password) connects to the FTP server host and creates FTP object f. If the host supports anonymous connections, you can use the host argument alone. To specify an alternate port, separate it from host with a colon (:).

Input Arguments

host	String enclosed in single quotation marks that specifies the FTP server.
username	String enclosed in single quotation marks that specifies your user name for the FTP server.
password	String enclosed in single quotation marks that specifies your password for the FTP server. Because FTP is not a secure protocol, others can see your user name and password.

Methods

ascii	Set FTP transfer type to ASCII
binary	Set FTP transfer type to binary
cd	Change or view current folder on FTP server
close	Close connection to FTP server
delete	Remove file on FTP server
dir	View contents of folder on FTP server
mget	Download files from FTP server
mkdir	Create folder on FTP server
mput	Upload file or folder to FTP server
rename	Rename file on FTP server
rmdir	Remove folder on FTP server

Copy Semantics

Handle. To learn how handle classes affect copy operations, see Copying Objects in the MATLAB Programming Fundamentals documentation.

Examples

Connect to the MathWorks FTP server, and display the FTP object:

mw=ftp('ftp.mathworks.com');
disp(mw)

MATLAB returns:

FTP Object
  host: ftp.mathworks.com
  user: anonymous
   dir: /
  mode: binary

Connect to port 34 (not supported at ftp.mathworks.com, so this code returns an error):

mw=ftp('ftp.mathworks.com:34')

Modify the following code to connect to a host that requires a password:

test=ftp('ftp.testsite.com','myname','mypassword')

Algorithms

The ftp function is based on code from the Apache Jakarta Project.
