mat2gray() followed by imwrite()
Note: true grayscale jpg are very uncommon in practice, but they have been valid for quite a while. They are not handled by some rather old browers (e.g., don't expect to display them easily in Windows XP time frame.)
In practice nearly all jpeg are RGB images.
Reminder: JPEG is a lossy image format, so if you expect to be able to read back in exactly what you wrote out, then you should use a different image format.
