Replacing repeated values in each row with zero

I have a matrix A:

A=[  2     4     6     7     8     9    10    28     6     9    10    11;
     2     4     6     7     8     9    10    28    10    21    22    24]

and I want to delete any repeated element in each row. The result should be as:

A=[  2     4     6     7     8     9    10    28     0     0    0    11;
     2     4     6     7     8     9    10    28     0    21    22    24]

Any idea? Thanks

Why do you want to do this? Is it homework? Are all A integers, or can they have fractional parts? Have you considered using histcounts() and look for numbers where the count is more than 2?

Thank you for the reply. No, it's not homework. The reason I want to do so is that each row has been created from previous processes and when I combine them (two rows combined to get the rows above), I get some of these repeated elements. The matrix I have is much greater in size than the one I mentioned. I haven't tried that function yet.

I forgot to add that all A are integer values, no fractional parts in it.
