3d plot scattered data of closed surface

Hi experts-

I have scattered 3D data of what will always be a closed surface. It may not always contain 0,0,0. I was looking into meshgrid here: http://www.mathworks.com/help/matlab/visualize/representing-a-matrix-as-a-surface.html#f0-9140 ...but the X and Y seemed returned in random order, so surf didn't take it. I see some complicated zip files I could explore, but I hope it's not too complicated. I'll even attach the actual data I'm trying to fit. Want to fit a closed surface to the scattered points.

Thanks so much in advance, Dave

You did not really define what you are trying to achieve. If you are just trying to do a scatter plot, then just load the data and then use scatter3()

Sorry, I edited the questions. Need to fit a closed surface to the scattered points.

If you have R2014b or later see http://www.mathworks.com/help/matlab/ref/boundary.html

If you have a mathematical model of the surface you might be able to do better.

Thanks. This is perfect with a hull setting, and edge color off. And more points :)
