I have very basic question regarding drawing stem plot for this example, it is supposed to have 21 data values.
T=4e-3; n=21;
x=linspace(0,T/2,2001);
x1=linspace(T/2,T,2001);
y=sin(pi*x/T);
y1=(1+cos(pi*x1/T));
plot(x,y,'b',x1,y1);
grid on; zoom on; hold on

T=4e-3; n=21;
% x=linspace(0,T/2,2001);
% x1=linspace(T/2,T,2001);
x=linspace(0,T/2,(n+1)/2);
x1=linspace(T/2,T,(n+1)/2);
y=sin(pi*x/T);
y1=(1+cos(pi*x1/T));
% plot(x,y,'b',x1,y1);
stem(x,y,'b');
hold on
stem(x1,y1);
grid on; zoom on;

This looks like a reasonable plot to me.
T=4e-3; n=21;
x=linspace(0,T/2,2001);
x1=linspace(T/2,T,2001);
y=sin(pi*x/T);
y1=(1+cos(pi*x1/T));
plot(x,y,'b',x1,y1);
grid on; zoom on; hold on
Let's plot it as a stem plot instead.
figure
stem([x,x1], [y,y1]);
There are too many stems to show each one as an individual line. Let's plot every 100 stems and see how that looks.
figure
stem([x(1:100:end), x1(1:100:end)], [y(1:100:end), y1(1:100:end)])
That looks nice to me.
