Hey!
I need to write this function , but i have tried it and it doesn't work.
Where am I wrong ?

The if function does not work like that.
You should try something like:
dt=0.01;
t=4;
T=0:dt:t;
p=zeros(size(T));
for i=1:length(T)
if T(i)>0 & T(i)<t/4
p(i)=sin(pi*T(i));
elseif T(i)>t/2 & T(i)<3*t/4
p(i)=1;
end
end
plot(T,p)

Thank you !
I will try

dt = 0.01;
t = 4;
T = 0:dt:t;
% First Quarter
r1 = 0:dt:t/4 ;
p1 = sin(pi.*r1) ;
plot (r1,p1)
% Define second Quarter here and append it to the above

Hey !
I tried this and the second quarter didn't work
clear
close all
clc
dt = 0.01;
t = 4;
T = 0:dt:t;
% First Quarter
r1 = 0:dt:t/4 ;
p1 = sin(pi.*r1) ;
figure(1)
plot (r1,p1)
hold on
% Second Quarter
r2 = t/4:dt:t/2
p2 = 0;
y = [r2 , p2]
figure(2)
plot(y)
hold off

% Second Quarter
r2 = t/4:dt:t/2
p2 = zeros(size(r2));
y = [p1 , p2]
figure(2)
plot([r1 r2],y)
Try it as above
