'''<big><big>Parameter Explanation</big></big>'''

* n : number of empty section.
* type : type1=triangle, type2=circle, type3=ellipse, type4=rectangular, type5=Sinkx function up, type6=Sinkx function down, type7=Sinkx function up, type8=Sinkx function down.
* f1-f6 : you can refer to the information where at bottom of this page.
* int_period_num :  
* f_period_spacing :  



'''<big><big>Example</big></big>'''

Type.1~4 are triangle, circle, ellipse and rectangle.

If the parameters are not show in the figure, you should set those parameters as 0.

Type5~8 are sine shape period structure. <br />

Type.5 and 6 can be determined by this expression:

<math>f_6<y<f_1sin(f_2x)+f_3;</math><br />

<math>f_4<x<f_5</math>

Type.7 and 8 can be determined by this expression:

<math>f_6<x<f_1sin(f_2y)+f_3;</math><br />

<math>f_4<y<f_5</math>
