说明：  1、 对一个等边三角形，每条边按照Koch曲线的方式进行迭代，产生的分形图称为Koch雪花。编制程序绘制出它的图形，并计算Koch雪花的面积，以及它的分形维数。 2、 自己构造生成元（要有创意），按照图形迭代的方式产生分形图，用计算机编制程序绘制出它的图形，并计算其分形维数。主要用MATLAB编程
(1, for an equilateral triangle, each side in accordance with Koch curve iterative manner, the resulting figure is called Koch snowflake fractal. Programmed to map out its graphics, and calculate the area of Koch snowflake, and its fractal dimension. 2, construct their own generators (the need for creativity), according to the way graphics iterative produce fractal images, using a computer programmed to map out its graphics, and calculate its fractal dimension.using MATLAB)
