Here is my code:
myaddress = 'example@gmail.com';
mypassword = 'example';
setpref('Internet','E_mail',myaddress);
setpref('Internet','SMTP_Server','smtp.gmail.com');
setpref('Internet','SMTP_Username',myaddress);
setpref('Internet','SMTP_Password',mypassword);
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');
sendmail(toexample@cornell.edu,'email subject test',...
'this email is a test','D:\testimagetosend.tif')
And here is the error message: Error using sendmail (line 171) Authentication failed.
From everything else I have read, the preferences and properties required for gmail are all taken care of, but still getting the error.

Within the last 8 months, Google turned off default support for an older less-secure authentication. You can re-enable it on your account... for now.

I'd like to add that if your use seems suspicious to google, it'll still fail the authentication attempt as suspicious activity.
Not sure how to work around this.

As of March 2022 Google has disabled this completely :/

For some service providers the extension ' @gmail.com' in myaddress may cause authentication error. Simply use userID.
