I'm a newbie on use of matlab and also in signals and systems. I need clarification and guide (with fundamental explanations please) on above.

I want to generate a sampled square wave in matlab with following criteria;

Signal duration T=5s, Sample frequency fs=40Hz. there are supposed to be fsT signal points (what does this mean please). tau=1/100. the square wave signals are zeros for the first fsT(1-tau)/2 points and also for the last fs*T(1-tau)/2 points. they are one otherwise.

What I have done so far:

clear all

fs = 40; t = [0:1/fs:5]; dc = 50; x = square(2pit); %f=1 for a square wave

plot (t,x);

Am I right? I have no idea how to use tau, and what signal points imply here. Kindly assist. Thank you.
