MATLAB: Remove rows of a table based on values in an array

remove rowstable

I want to remove all rows from a table, when a value in table.variable appears only once.
For example
table:
var1 | var2 | var3
1 | 2 | 0
1 | 2 | 3
1 | 2 | 3
1 | 2 | 8
4 | 5 | 8
1 | 2 | 9
should become
var1 | var2 | var3
1 | 2 | 3
1 | 2 | 3
1 | 2 | 8
4 | 5 | 8

disp('Original table');
var1=[1;1;1;1;4;1];
var2=[2;2;2;2;5;2];
var3=[0;3;3;8;8;9];
table_data=table(var1,var2,var3)
n=histc(var3(:),var3);
disp('Updated table');
table_data(find(n==1),:)=[]
