A cobweb plot, or Verhulst diagram is a visual tool used in the dynamical systems field of mathematics to investigate the qualitative behaviour of one-dimensional iterated functions, such as the logistic map. Using a cobweb plot, it is possible to infer the long term status of an initial condition under repeated application of a map. ==Method== For a given iterated function ''f'': R → R, the plot consists of a diagonal (x = y) line and a curve representing y = f(x). To plot the behaviour of a value , apply the following steps. # Find the point on the function curve with an x-coordinate of . This has the coordinates (). # Plot horizontally across from this point to the diagonal line. This has the coordinates (). # Plot vertically from the point on the diagonal to the function curve. This has the coordinates (). # Repeat from step 2 as required. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Cobweb plot」の詳細全文を読む スポンサード リンク
