As the title says for some reason square command has too many input arguments I don't know why. Done the same example a while ago and all worked.
tmax=9e-3;
T=3e-3;
Umax=2;
Umin=-3;
N=19;
a=0.6;
wo=(2*pi)/T;
t=linspace(0,tmax,2001);
U=square(wo*t,100*a);
U=0.5*(Umax-Umin)*U+0.5*(Umax+Umin);
td=linspace(0,tmax,N);
Ud=square(wo*td,100*a);
Ud=0.5*(Umax-Umin)*Ud+0.5*(Umax+Umin);
close all;
plot(t,U,'b');
grid on; zoom on; hold on;
stem(td,Ud,'r*');

Code is working fine. It seems you have introduced a variable named square. Clear it and then run the function. REad about clear
clear square
tmax=9e-3;
T=3e-3;
Umax=2;
Umin=-3;
N=19;
a=0.6;
wo=(2*pi)/T;
t=linspace(0,tmax,2001);
U=square(wo*t,100*a);
U=0.5*(Umax-Umin)*U+0.5*(Umax+Umin);
td=linspace(0,tmax,N);
Ud=square(wo*td,100*a);
Ud=0.5*(Umax-Umin)*Ud+0.5*(Umax+Umin);
close all;
plot(t,U,'b');
grid on; zoom on; hold on;
stem(td,Ud,'r*');
