How can i implement a clock series?

This is my code i used for matlab function block and it goes straight to scope .But it does not work in the scope.

function [Th1,Th2] = fcn(t)

if (0<t)&&(t<10)

Th1 = 0;Th2=0;

elseif (10<t)&& (t<11.2)

Th1 = 100;Th2=100;

elseif (11.2<t)&&(t<12.5)

Th1 = 100;Th2=50;

elseif (12.5<t)&&(t<13)

Th1 = 80;Th2=53;

elseif (13<t)&&(t<13.8)

Th1 = 60;Th2=36;

elseif (13.8<t)&&(t<25.1)

Th1 =100;Th2=100;

elseif (25.1<t)&&(t<26)

Th1 = 55;Th2=100;

elseif (26<t)&&(t<33.5)

Th1 = 0;Th2=10;

elseif (33.5<t)&&(t<50)

Th1 = 0;Th2=0;

else

Th1 = 0;Th2=0;

end
