Frees a BLACS context.
base.gridexit(ICTXT, override = FALSE)gridexit(ICTXT, override = FALSE)
BLACS context number.
logical; if TRUE, ignores normal check preventing the
closing of ICTXT values of 0, 1, and 2. This could cause things
to go crazy and I do not recommend it.
Silently returns 0 when successful. Silently returns 1 when
requested ICTXT does not exist.
For advanced users only. See pbdDMAT for high-level functions.
The function frees the requested BLACS context. It is a trivial wrapper for
the BLACS routine BLACS_GRIDEXIT. Also removes the object
.__blacs_gridinfo_ICTXT.
Contexts 0, 1, and 2 can not be freed in this way unless the argument
override=FALSE. This will probably break something and I do not
recommend it.
