%    subject of the message, and MESSAGE is the content of the message to
%    send.

%         'Calculation Done','Don't forget to retrieve your result file')
%      send_text_message('234-567-8910','Cingular', ...
%         'This is a text message without subject')

%% Set up Gmail SMTP service.
% Note: following code found from
% http://www.mathworks.com/support/solutions/data/1-3PRRDV.html
% If you have your own SMTP server, replace it with yours.

% Then this code will set up the preferences properly:
setpref('Internet','E_mail',mail);
setpref('Internet','SMTP_Server','smtp.gmail.com');
setpref('Internet','SMTP_Username',mail);
setpref('Internet','SMTP_Password',password);

% The following four lines are necessary only if you are using GMail as
% your SMTP server. Delete these lines wif you are using your own SMTP
% server.
props = java.lang.System.getProperties;
props.setProperty('mail.smtp.auth','true');
props.setProperty('mail.smtp.socketFactory.class', 'javax.net.ssl.SSLSocketFactory');
props.setProperty('mail.smtp.socketFactory.port','465');

%% Send the email
sendmail(emailto,subject,message)

if strcmp(mail,'matlabsendtextmessage@gmail.com')
    disp('Please provide your own gmail for security reasons.')
    disp('You can do that by modifying the first two lines of the code')
