Or you can directly copy and paste the file into Resampling from your browser. If this is the way you selected then simply click on the below link and the program will appear.

You will need to edit the program to the appropriate parameters that are given in the actual lesson. This is a list of the variable names and what they mean.

• set 1 10 L --- A plate of length 10.
• set 1 5 M --- A plate of height 5.
• set 1 4 xpoint --- The x-coordinate of interest.
• set 1 2 ypoint --- The y-coordinate of interest.
• set 1 0 left --- The temperature of the left edge.
• set 1 0 right --- The temperature of the right edge.
• set 1 0 bottom --- The temperature of the bottom edge.
• set 1 50 top --- The temperature of the top edge.
• set 1 100 walks --- The number of random walks.
In the lesson you will be asked to change the various parameters to different values. All you need to do is change the number (10, 5, 4, etc..). Leave the rest of the program alone.

Once the program is set, go to the RUN menu and select EXECUTE. The program will then run the trial for you and show the results. The result window will show something like this.

• XMAX = 2
• XMIN = 16
• YMAX = 39
• YMIN = 43
• TEMP = 19.5
• NUM = 100
XMAX signifies how many times the random walk reached the right edge, XMIN the left edge, YMAX the top edge and YMIN the bottom edge. TEMP is the temperature of the point of interest and NUM is the number of random walks.

Occasionally, the program will give no results for a large number of random walks. If this happens execute program again.
