Hi all.
I am not quite sure on how to use scatteredInterpolant. I tried reading up on it, but it doesn't make sense to me since I don't have a function v. All I have are points that I need plotted/interpolated. I attached a csv document with some sample data (not actual values, just place holders). Thanks for any help.

You appear to be wanting to do an 11-dimensional scattered interpolation. Unfortunately MATLAB does not have any scattered interpolation routines that work in more than 3 dimensions, but gridded interpolation can. In a previous discussion Kelly provided a means to convert a scattered vector to gridded information, but it can potentially take up a lot of memory.
On the other hand, you indicate that you want to be able to plot this. There is no way you will be able to plot in 11 dimensions: there are not enough graphics attributes available for more than about 7 dimensions (not saying the plot would be easy to read for that many dimensions...)

Are you sure that this would be 11 dimensional? If you look at the breakpoints in the 1st column and assume these to be x coordinates, and the breakpoints in the 1st row and assume these to be y coordinates, wouldn't it be possible to graph the stuff mapped to these values on the z axis? Making this 3d, where scatteredinterpolant would work. (F(x,y)=z type relationship).

Ummm, it is your data file, and you said the points were in the file, without specifying rows or columns...
