C Purpose
|
|
C =======
|
|
C
|
|
C Performing column permutation of a sparse matrix.
|
|
C
|
|
C Parameters
|
|
C ==========
|
|
C
|
|
C TRANS - CHARACTER*1
|
|
C On entry TRANS specifies whether the routine will use
|
|
C matrix P or the transpose of P for the permutation as follows:
|
|
C TRANS = 'N' -> permute with matrix P
|
|
C TRANS = 'T' or 'C' -> permute the transpose of P
|
|
C Unchanged on exit.
|
|
C
|
|
C M - INTEGER
|
|
C On entry: number of rows of matrix A.
|
|
C Unchanged on exit.
|
|
C
|
|
C N - INTEGER
|
|
C On entry: number of columns of matrix A.
|
|
C Unchanged on exit.
|
|
C
|
|
C DESCRA - CHARACTER*5 array of DIMENSION (10)
|
|
C On entry DESCRA defines the format of the input sparse matrix.
|
|
C Unchanged on exit.
|
|
C
|
|
C A - DOUBLE PRECISION array of DIMENSION (*)
|
|
C On entry A specifies the values of the input sparse
|
|
C matrix.
|
|
C Unchanged on exit.
|
|
C
|
|
C IA1 - INTEGER array of dimension (*)
|
|
C On entry IA1 holds integer information on input sparse
|
|
C matrix. Actual information will depend on data format used.
|
|
C Unchanged on exit.
|
|
C
|
|
C IA2 - INTEGER array of dimension (*)
|
|
C On entry IA2 holds integer information on input sparse
|
|
C matrix. Actual information will depend on data format used.
|
|
C Unchanged on exit.
|
|
C
|
|
C INFOA - INTEGER array of dimension (10)
|
|
C On entry can hold auxiliary information on input matrices
|
|
C formats or environment of subsequent calls.
|
|
C Might be changed on exit.
|
|
C
|
|
C P - INTEGER array of dimension (M)
|
|
C On entry P specifies the column permutation of matrix A
|
|
C (P(1) == 0 if no permutation).
|
|
C Unchanged on exit.
|
|
C
|
|
C WORK - DOUBLE PRECISION array of dimension (LWORK)
|
|
C On entry: work area.
|
|
C On exit INT(WORK(1)) contains the minimum value
|
|
C for LWORK satisfying DSPRP memory requirements.
|
|
C
|
|
C LWORK - INTEGER
|
|
C On entry LWORK specifies the dimension of WORK
|
|
C Unchanged on exit.
|
|
C
|
|
C IERROR - INTEGER
|
|
C On exit IERROR contains the value of error flag as follows:
|
|
C IERROR = 0 no error
|
|
C IERROR > 0 warning
|
|
C IERROR < 0 fatal error
|
|
C WORK - DOUBLE PRECISION array of dimension (LWORK)
|
|
C Work area.
|
|
C
|
|
C LWORK - INTEGER
|
|
C On entry LWORK specifies the dimension of WORK.
|
|
C LWORK must be greater than zero.
|
|
C On exit LWORK is the maximum between the initial value and
|
|
C the minimum value satisfying DSPRP memory requirements.
|
|
C
|
|
C IERROR - INTEGER
|
|
C On exit IERROR contains the value of error flag as follows:
|
|
C IERROR = 0 no error
|
|
C IERROR = 4 error on dimension of vector WORK
|
|
C IERROR = 32 unknown flag TRANS
|
|
C IERROR = 64 LWORK <= 0
|
|
C IERROR = 128 this data structure not yet considered
|
|
C
|
|
C Notes
|
|
C =====
|
|
C It is not possible to call this subroutine with LWORK=0 to get
|
|
C the minimal value for LWORK. This functionality needs a better
|
|
C connection with DxxxMM
