* 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 - MPI 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.
