## Main Question or Discussion Point

I have some experimentally determined data, and have been asked if it is possible to create a 3-d model of a mound, showing temperature changes from the center. The data I have been given are; depth, and corresponding temperatures, organized in six columns, depth, temp for N,S,E,W, and one for the center of the mound. Depth was measured at 10cm distances from the top of the mound, and temperature readings were taking every 10 cm from the center of the mound to the outer edge.

Depth (cm)

10 27 23.5 29 31 25

20 27 22 29 31 25

30 29 23 30 32 26

40 31 26 31 34 28

50 33 28 32.5 36 30

60 35 29.5 34 38 31

70 37 31 35.5 39 32.5

80 38 32.5 36.5 39.5 34

90 39 34 37.5 40 35

100 39 34.5 38 40 35.5

110 39 34.5 38 40 35.5

120 39 35 37.5 40 35.5

I have tried using scatter3, and I have tried using meshgrid, (inputting the distance for each thermal temperature as the x value) but I am thinking I need help in creating a coordinate system with the variables I have been given. Can I help the student attempting this research with the data he has, create a model of his compost heap without a z value, in Matlab.
