Something like this?
y=load('Data.mat').pdw;
y0=y(:,5)==0;
y1=y(:,5)==1;
plot(y(y0,1),y(y0,2))
hold on
plot(y(y1,1),y(y1,2))
legend({'Corresponding to Zero', 'Corresponding to One'})
There are some repetetive values in the data, as seen by the graph.

%numbers of 0
n0=nnz(y0)
n0 = 9479
%numbers of 1
n1=nnz(y1)
n1 = 434
Use fprintf or sprintf if you actually want to print the values
