detailed documentation

control derived type as a Julia structure

components

Bool f_indexing

use C or Fortran sparse matrix indexing

INT error

error and warning diagnostics occur on stream error

INT out

general output occurs on stream out

INT print_level

the level of output required is specified by print_level

INT max_col

maximum permitted number of nonzeros in a column of \(A\); -ve means unlimit

INT new_a

how much has \(A\) changed since it was last accessed:

• 0 = not changed,

• 1 = values changed,

• 2 = structure changed

• 3 = structure changed but values not required

INT extra_space_s

how much extra space is to be allocated in \(S\) above that needed to hold the Schur complement

Bool s_also_by_column

should s.ptr also be set to indicate the first entry in each column of \(S\)

Bool space_critical

if .space_critical true, every effort will be made to use as little space as possible. This may result in longer computation time

Bool deallocate_error_fatal

if .deallocate_error_fatal is true, any array/pointer deallocation error will terminate execution. Otherwise, computation will continue

NTuple{31,Cchar} prefix

all output lines will be prefixed by .prefix(2:LEN(TRIM(.prefix))-1) where .prefix contains the required string enclosed in quotes, e.g. “string” or ‘string’
