How do I create and plot a pulse train from an existing pulse not using the pulse train function?

I have a pulse which uses a hann window and lasts 100 micro seconds. I need to create a pulse train over a period of a about 1 millisecond. I just need help with knowing what to put as my twin as you will see in the code below. With the twin I'm using I get an error:

??? Error using ==> plot
Vectors must be the same lengths.

How do I resolve this error?

fs = 1.5e6;%sample rate of 1,500,000
twin= 0: (1/150)/fs: 10e-3;
tpulse = ([1:150]-1)*(1/fs);
fc =130e3;%centre frequency of 130kHz
w = 2*pi*fc;%omega
y = real(exp([-1i*w*tpulse]));%sin wave
subplot(411);
plot(tpulse,y);
a = hann(150);%hanning window to give it click profile
y2 = y.*a';
subplot(412);
plot(twin,y2);
Y = fft(y2);
subplot(413);
plot(abs(Y));
subplot(414);
plot(y2);

One of the correct ways to define the pulse and the train is:

tpulse = 0:1/fs:100e-6; %100 micro seconds
twin=    0:1/fs:  1e-3; %1 mili second

The rest of the code needs to be fixed, I wonder if:

fs = 1.5e6;%sample rate of 1,500,000
tpulse = 0:1/fs:100e-6; %100 micro seconds
twin=    0:1/fs:  1e-3; %1 mili second
fc =130e3;%centre frequency of 130kHz
w = 2*pi*fc;%omega
y = real(exp([-1i*w*twin]));%sin wave
subplot(411);
plot(twin,y);
a = hann(numel(twin));%hanning window to give it click profile
y2 = y.*a';
subplot(412);
plot(twin,y2);
Y = fft(y2);
subplot(413);
plot(abs(Y));
subplot(414);
plot(y2);

Here's a way to create twin from tpulse

twin=tpulse:1/fs:1e-3; %1 mili second

and a way to create tpulse from twin

tpulse=twin(1:find(twin==1e-3))
