Can I use the code in Matlab?

The code here is really neat and concise, however one thing I would reccomend is editing the graph such that the triangle is equilateral as a true soil-texture triangle would be. Additionally, putting in grid lines and labels would be helpful for those that would want to see the percentages of each material (silt, sand, clay).
