* Routine: DMOUT
|
|
*
|
|
* Purpose: Real matrix output routine.
|
|
*
|
|
* Usage: CALL DMOUT (LOUT, M, N, A, LDA, IDIGIT, IFMT)
|
|
*
|
|
* Arguments
|
|
* M - Number of rows of A. (Input)
|
|
* N - Number of columns of A. (Input)
|
|
* A - Real 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.
