Geometrically an eigenvector, corresponding to a real nonzero eigenvalue, points in a direction that is stretched by the transformation and the eigenvalue is the factor by which it is stretched. If the eigenvalue is negative, the direction is reversed.
For example, if the population doubles every 5 days, this can be represented as an exponential function. Most population models involve using the number e. To learn more about e, click here (link to exp-log-e and ln.doc) Population models can occur two ways. One way is if we are given an exponential function.
