Lets say sample rate =20kHz symbol rate =1khz

Make up one cycle, then use repmat() to make as many copies as you want.
squareWave = repmat([1,1,1,1,0,0,0,0], [1, N]);
What is a "symbol rate"?

You can either write the function or use built-in function, here is an example using 1000 samples :
N=1e+3;
Fs=20e+3;
f=1e+3;
Ts=1./Fs;
t=0:Ts:N*Ts-Ts;
y=square(2*pi*f*t);
figure; plot(t,y);

You are using square function to generate square wave, what i want is square pulse in discrete form. I am confused using pulstran @rectpuls as it generates continuous rectangular pulses

Yes, square() is in the Signal Processing Toolbox - do you have that toolbox? I have not heard of those two other functions you mention.
