I'm encountering a problem when using sendmail to include an image attachment. I have sendmail set up so that it works. When I have a plot, I can send it by typing the following in the command window

print(gcf,'-dpng','-r0','bargraph.png')
sendmail('fishbacp@mail.gvsu.edu','Bargraph from script attached','bargraph.png')

However, when I try to include the above lines within a script, the actual image is not attached. Instead, I receive the email but it merely has "bargraph.png" appearing as the message body.

Thank you so much. Am I correct that your code prompts the use to specify the attachment directory, as described below the line

%------------ Attach file ----------

I'm curious to know if there's a simpler way to do this so that I can let a script run for several hours (or couple of days) and then return to find that the image attachment has automatically been sent to my inbox.

@Patrick Callahan, not sure what "hoes mad" means. My hoes at least are perfectly happy hanging up in my garage, they're not mad at all. I'm not sure about your hoes.

send_email.m

See attached demo. Make the trivial, obvious changes and it should work.
