MatLab Newbie: How do I import a set of 3d points?

[RedK24]

I have very little experience in MatLab but this seems to be the best tool to create the graphics I need to present my data.

I have 100 different (x,y,z) triplets, these are all individual points. I cannot get them imported as a set of 100 individual 3D points. I have them all in text files and spreadsheets in multiple formats. The only way I have been able to import this data is as a matrix. I have tried plotting these using surf, mesh, meshgrid xy..., etc. but it always comes out wrong.

I actually have 20 separate sets of data like this I need to graph.

the xy plane is just a 10x10 grid with a point at each integer value and the z is a number that has already been created from my data (z is the vertical axis). the range of z is relatively small.

I need to create a colored 3d surface image from all these points.

There are no adjustments to make to these points.

I hope this was clear enough.
If anyone can help me out it would be very appreciated, I have spent the better part of my workday wrestling with this. Thanks!
