### Remark

You can download a MATLAB implementation of The Fire Tower
at the following link: firetower.
In order to run the program you must also download the file
cube. The program is an illustration of
the article. It is meant to be a help for your studies. It is
not mandatory that you can explain what is going on in the program.

In the article there is a formula for the height of a twelve
cube tower on page 49. Here a summation formula is used at the
last equality sign. The note sum explains
this summation formula.

The MATLAB file N illustrates how one can transform
a wire-frame model of the letter N. A complicated example of a
3D wire-frame model can be found at
