In mathematics, the blancmange curve is a fractal curve constructible by midpoint subdivision. It is also known as the Takagi curve, after Teiji Takagi who described it in 1901, or as the Takagi–Landsberg curve, a generalization of the curve named after Takagi and Georg Landsberg. The name ''blancmange'' comes from its resemblance to a pudding of the same name. It is a special case of the more general de Rham curve. ==Definition== The blancmange function is defined on the unit interval by : where is the triangle wave, defined by for a parameter ''w''; thus the blancmange curve is the case . The value is known as the Hurst parameter. The function can be extended to all of the real line: applying the definition given above shows that the function repeats on each unit interval. 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「Blancmange curve」の詳細全文を読む スポンサード リンク
