I have question regarding fft function in matlab. If I do something like:

t = 0:0.001:0.6;
x = sin(2*pi*50*t)+sin(2*pi*120*t);
y = x + 2*randn(size(t));
plot(1000*t(1:50),y(1:50))
title('Signal Corrupted with Zero-Mean Random Noise')
xlabel('time (milliseconds)')

Then which window is being used by MATLAB. I looked into help of fft function but there is nothing said about it.
 

where is the fft in ur code?

If you mean what window is used when drawing a part of the signal in time domain, I think it is a rectangular window
