* * Routine: PCMOUT - Parallel Version of ARPACK utility routine CMOUT * * Purpose: Complex matrix output routine. * * Usage: CALL PCMOUT (COMM, LOUT, M, N, A, LDA, IDIGIT, IFMT) * * Arguments * COMM - BLACS Communicator for the processor grid * M - Number of rows of A. (Input) * N - Number of columns of A. (Input) * A - Complex M by N matrix to be printed. (Input) * LDA - Leading dimension of A exactly as specified in the * dimension statement of the calling program. (Input) * IFMT - Format to be used in printing matrix A. (Input) * IDIGIT - Print up to IABS(IDIGIT) decimal digits per number. (In) * If IDIGIT .LT. 0, printing is done with 72 columns. * If IDIGIT .GT. 0, printing is done with 132 columns. * * FILE: mout.F SID: 1.1 DATE OF SID: 3/19/97 RELEASE: 1 * *----------------------------------------------------------------------- * SUBROUTINE PCMOUT( COMM, LOUT, M, N, A, LDA, IDIGIT, IFMT ) * ... * ..
