title: MATLAB create title over one column of subplot
body: <p>So I have a 3x3 array of subplots.  I know how to get a title on each one of them, and I know how to get a "super title" using the suptitle function over the whole thing, but I can't figure out how to get titles to only show up over each column.  I also want to do a similar thing with the rows.  Think hip, knee, ankle across the top, then angular velocity, torque, and power down the left side.  Thoughts?</p>
