156121-test_polar

  这可是我两年前用matlab写的第一个函数，算是处女作。 这个例子涉及三角函数的系数变换及其极坐标系绘图，以及界面和控件的颜色修改。(But I used it two years ago to write the first matlab function can be regarded as a debut. This example involves the coefficient of trigonometric function transform and its polar coordinates drawings, as well as the interface and control color modify.)
