Poisson distribution and discrete distribution

Hello guys,

I have two set of data, the first one I have to fit it to a Poisson distribution while the second one I have to fitted to a discrete distribution. Does any one know how to do it and how I can get the coefficients?

Thanks in advance

% I want to fit X to a Poisson distribution
x=[
    5
    16
    43
    25
    19
    5
    3
    ];
X=x/sum(x);
bar(X)

figure 
% I want to fit Y to a Discrete distribution
y=[
    150
    93
    50
    38
    26
    27
    10
    7
    6
    5
    ];

Y=y/sum(y);
bar(Y)

The Poisson distribution is a discrete distribution...

fitdist allows you to fit a distribution to data.

There are an infinite number of different forms of discrete distribution; you are going to need to be more specific about what Discrete distribution means in this context.
