title: Matlab 3D data interpolation
body: <p>I have a set of x,y and z data (each is a 3000 by 1 matrix) and I would like to interpolate this data to have a set of values for the z height at evenly spaced x and y values. I assume I need to mesh grid the x and y data sets, but I don't know how to interpolate for the z data. The data points are the unique vertices taken from an STL file, and so I'm looking to smooth out the resulting surface.</p>
  
  <p>Any help much appreciated , </p>
