Plotting with different step

Hello I have 2 vectors:

A which is 1x32000

B which is 1x2000

I need to plot them with a different step so they match, in other words i need for B to plot a value once for every 16 values of A.

Whenever I do:

hold on

plot (s)

stem (fn)

hold off

One would basically end after 2000 steps and the other one after 32000 however I would like for both of them to end at 32000 is there a way to do so?

t32 = linspace(0,2,32000+1); t32(end) = [];  %remove time 2 exactly
t8 = linspace(0,2,800+1); t8(end) = [];   %remove time 2 exactly

s = sin(t32*pi*50);  %one signal
fn = sin(t8*pi*23) + cos(t8*pi*17);  %another signal

plot(t32, s);
hold on
stem(t8, fn);
hold off

Thank you, exactly what I needed.
