| Abstract: | Using rough information matrix this concept, singular rough information matrix was put forward and its mathematical structure properties were given. One direction singalar rough information matrix and both direction singular rough information matrix are two forms of S-rough information matrix. The relation theorems among an S-rough information matrix, rough information matrix, S-rough sets and Z. Pawlak rough sets were presented. |

| Keywords: | information matrix rough information matrix dual of one direction singalar rough information matrix structures of S-mngh information matrix |
