In the example about the French coast guard in this section, suppose you are a spy watching the boat and listening in on the radio messages from the boat. You collect the following data: 53 • When the actual position is 41 they radio 88 7 54 • When the actual position is they radio 40 87 Can you crack their code (i.e.., find the coding matrix), assuming that the code is linear?

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
