In accordance with a parallel matrix processing method adopted in a shared-memory scalar computer, a matrix to be subjected to LU factorization is divided into a block D of the diagonal portion and blocks beneath the D diagonal block such as L1, L2 and L3. Then, D+L1, D+L2 and D+L3 are assigned to 3 processors respectively for processing them in parallel. Next, a block U is updated by adopting an LU-factorization method and C1 to C3 are updated with L1 to L3 and U. By carrying out this processing on the inner side gradually decreasing in size as blocks, finally, a portion corresponding to the D diagonal block remains to be processed. By applying the LU factorization to this D portion, the LU factorization for the entire matrix can be completed.

Message data are picked up by using a decoder 2 from received signals received by a receiver portion 1 of a radio paging receiver, and stored in a RAM 4a of a CPU 4. An informing portion 9 informs a user of the message. The user designates any character sequences in the message stored in the RAM 4a by a character sequence designating unit 4b. A character sequence retrieving unit 4c retrieves whether or not designated character sequences are contained in stored messages. When the messages containing the designated character sequences are detected, a time counting unit 4d monitors whether or not a predetermined time has been lapsed after storage of concerned messages. An erasing unit 4e erases unnecessary messages stored in the RAM 4a from the RAM 4a after the predetermined time has been lapsed. Accordingly, the messages which are transmitted periodically and repeatedly to the radio paging receiver can be erased collectively and automatically and thus complicatedness in erasing the messages can be eliminated and also operability can be enhanced.
