57 // <synopsis>
58 // A <src>Poisson</src> is described by lambda
59 // The value is:
60 // <srcblock>
61 // height (|x-center| == 0.0)
62 // 0 (|x-center| != 0.0)
63 // </srcblock>
64 // The parameters are enumerated by LAMDA. They have
65 // default values of 1.
66 // </synopsis>

68 // <example>
69 // <srcblock>
70 // PoissonFunction<Double> sf(5.0);
71 // sf(25); // = 5.0
