Here is one way:
t = linspace(0,10*pi,1000);
s = sin(t);
sn = 0.3*cos(t./4);
figure(1)
subplot(2,1,1)
plot(t, s)
title('Signal with constant baseline')
grid
subplot(2,1,2)
plot(t, s+sn)
title('Signal with with wandering baseline')
grid

Change this line to produce a 20-element vector:
t = linspace(0,10*pi,20)';
sn = 0.5*cos(t./3)*(max(A)-min(A));
figure(1)
plot(A,'-b')
hold on
plot(A+sn,'-r')
hold off
The sn assignment generates the baseline noise, so all you need to do to generate your code with a wandering baseline is to add your signal to it. This code should work for your signal. Only you know what you need, so feel free to change it as necessary.
