how to generate repeated function with failure like this in picture?

I want to plot this repeating function with this periodic failure. I have plotted this function without this fail. if any one can help, pleassss!

the function i have do to plot the periodic trapizoid is:

function p=fnpw1(omg1)

omg1=mod(omg1,0.1847);

if omg1 <=0.015392

%p=4.43;

p=4+(0.43*(omg1)/0.015392);

elseif omg1>0.015392 && omg1<0.030784

p=4+(0.43);

elseif omg1>=0.030784 && omg1<0.046176

p=4+(-27.93659*(omg1)+1.29);

elseif omg1>=0.046176

p=4;

end

I have tried to solve it again, i think this code has solved it

function I =fnpwtf3(omg1)

omg2=mod(omg1,2*pi) ;

omg1=mod(omg1,0.1847) ;

safe_cond_up =omg1 <=0.015392 ;

safe_cond_st = omg1>0.015392 & omg1<0.030784;

safe_cond_dn = omg1>=0.030784 & omg1<0.046176;

safe_cond_msc=omg1>=0.046176 ;

p_up=4+(0.43*(omg1)/0.015392);

p_st=4+(0.43);

p_dn=4+(-27.93659*(omg1)+1.29);

p_msc=4 ;

fail_cond = omg2>0.7391982716 & omg2<=1.524596435;
