i have this code but i do not knew how to run it

function y=quantr(b,x) delta=2./(2.^b); s=zeros(1,2^b); s(1)=-1+delta/2; for n=2:(2^b) s(n)=s(n-1)+delta; end y=zeros(size(x)); for k=1:length(x) p=1; while (abs(x(k)-s(p))>0.5*delta) p=p+1; end y(k)=s(p); end end

-----------------

x=-1:0.001:1; y=quantr(4,x); plot(x,y) xlabel('input'); ylabel('quantized output');
