MATLAB Mobile has a neat feature that allows you to e-mail a saved figure snapshot as a PNG file, with just two taps! You can try it out: from a snapshot in the History tab or an individual interactive figure in the Figures tab, just tap the action button in the upper-right. <\/p>\n

\n\"Steps\n<\/div>\n

This is a neat feature, but what if you don't have MATLAB Mobile? Wouldn't it be great if you an email a figure image right from MATLAB? Of course you can! MATLAB has a handy sendmail<\/tt><\/a> function that uses your email SMTP server to send an email with attachments. I've most commonly seen this function used to email the results after a long simulation or to send nightly reports, but it can also be used to send pictures. <\/p>\n

Using sendmail<\/tt>'s attachment functionality combined with the magical print<\/tt><\/a> function, in two steps we can save a figure to disk and then attach it to an outgoing email. In the following code we use the current figure gcf<\/tt> but any figure handle can be supplied. <\/p>\n

print(gcf,'-dpng'<\/span>,'-r0'<\/span>,'figure.png'<\/span>)\r\nsendmail('my.friend@example.com'<\/span>,'Look at this cool figure'<\/span>,'Hey man, check out what I did with MATLAB!'<\/span>,'figure.png'<\/span>)<\/pre>\n
Now that I think about it, \"Figures with Friends\" sounds like a good idea for my next mobile app. <\/p>\n","protected":false},"excerpt":{"rendered":"

The one gotcha is that is that sendmail<\/tt> requires a one-time set-up of your email account. The details for setting the server and username are in the sendmail documentation<\/a>.<\/p>\n
