MATLAB: Comparing columns and returning 0s for matching values

comparing values

I have two columns in two separate tables:
T1 - Col A      T2 - Col A
1      1
2      4
3    `  5
4      
5
I am looking to create in table 1 a column B containing zeros for those matching values between T1-colA and T2-colA.
The result will look like
T1 - Col A      T1 - Col B
1      0
2      
3    `  
4      0
5      0
How could I accomplish this efficiently?

is it a table that you have or an array? Have you looked into ismember to see if this does what you want?
