How to plot a probability mass function in matlab

I am new to matlab and would like to know how to plot a graph when it states

a =  -1    0   1       2       3
----------------------------------
p(a)1/24  1/2  1/4   1/6     1/24

Any tips on how to do it would be helpful!

Because this shows up high when searching for MATLAB PMF, an alternative way to plot discrete probability distributions is the stem function.

a = [-1 0 1 2 3]; p = [1/24 1/2 1/4 1/6 1/24];
stem(a,p);
set(gca, 'xlim', [-1.5 3.5]);

For a probability mass function, I would use bar

>> a = [-1 0 1 2 3]; p = [1/24 1/2 1/4 1/6 1/24]; bar(a,p)
