Removing duplicate observations in a Matrix where the rows are not completely identical

Hi,

I have Matrix A, where many rows are like in the attached image. column 1 is the id of the company and column 2 is the date of the data. How can I remove row 2,which is a duplicate of row 1 but row one has more complete data. The matrix is full with these rows that belong to the same company on the same date. Any help is greatly appreciated.

so you fix....any one number (may be the first column), get the indices and remove them.
