title: 4 dimensional plot in matlab
body: <p>I am trying to create a plot in Matlab with my 4 dimensional data. the data looks like [x,y,z,d] in which x,y and z are the coordinates of the object and "d" is the intensity. I tried to map the data and consider just [x,y,d] and do contour or surf but for that "d" should be a matrix. I also used plot3 but it does not look nice or like a contour. Any idea how to plot this in a nice way? 
  Here is an example of the data:</p>
