Subject:      Change some values to zero in a matrix
Content-Type: TEXT/PLAIN; charset=US-ASCII

Hi,

Does anyone know how to change certain values to zero in a Matrix in SAS
for example,  I have   1 2 3 4
                       5 6 7 8
                       4 3 2 1
                       8 7 6 5
I want to change matrix to   1 2 3 4
                             5 6 7 0
                             4 3 0 0
                             8 0 0 0
And do it for a lot of matrix.
THanks a lot
