The second solution can be disregarded since distance from the station cannot be negative. For a LORAN system to accurately position a ship using this system of equations, the ship will need to first have a general idea of where it is in relation to the stations to select the appropriate solution. It should be noticed that the as the initial guess increases the answers fluctuate between the possible solutions. Below are the outputs of the program. >> L13P1copy AnswerNumber = 1 InitialGuess = 10 10 x = 1.0e+002 * 2.542211204388131 2.193069916050682 ans = 0 0 AnswerNumber = 2 InitialGue...
