Please provide the Matlab code for these two functions

% (prz.m) % generating a rectangular pulse of width 1/2 & Usage function pout=prz (T); function pout=prz (T); pout=[zeros(1, T/4) ones (1, T/2) zeros(1, T/4)); end % (psine.m) % generating a sinusoid pulse of width T % function pout=psine (T); pout=sin(pi* [0:T-1]/T); end
