$emptyperiodshape is a function that you can set difference empty shape for period. It is the same as $emptyperiodtriangle

Format

$emptyperiodshape 
n
type1 f1 f2 f3 f4 f5 f6 int_period_num f_period_spacing


Parameter Explanation

  • 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 :


Example

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.

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

f_6<y<f_1sinf_2x+f_3;

f_4<x<f_5

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

f_6<x<f_1sinf_2y+f_3;

f_4<y<f_5
