If Octave for some reason exits unexpectedly it will by default save the
variables available in the workspace to a file in the current directory.
By default this file is named ‘octave-workspace’ and can be loaded
into memory with the load command. While the default behavior
most often is reasonable it can be changed through the following
functions.
val = crash_dumps_octave_core () ¶old_val = crash_dumps_octave_core (new_val) ¶old_val = crash_dumps_octave_core (new_val, "local") ¶Query or set the internal variable that controls whether Octave tries to save all current variables to the file octave-workspace if it crashes or receives a hangup, terminate or similar signal.
When called from inside a function with the "local" option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
See also: octave_core_file_limit, octave_core_file_name, octave_core_file_options.
val = sighup_dumps_octave_core () ¶old_val = sighup_dumps_octave_core (new_val) ¶old_val = sighup_dumps_octave_core (new_val, "local") ¶Query or set the internal variable that controls whether Octave tries to save all current variables to the file octave-workspace if it receives a hangup signal.
When called from inside a function with the "local" option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
val = sigquit_dumps_octave_core () ¶old_val = sigquit_dumps_octave_core (new_val) ¶old_val = sigquit_dumps_octave_core (new_val, "local") ¶Query or set the internal variable that controls whether Octave tries to save all current variables to the file octave-workspace if it receives a quit signal.
When called from inside a function with the "local" option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
val = sigterm_dumps_octave_core () ¶old_val = sigterm_dumps_octave_core (new_val) ¶old_val = sigterm_dumps_octave_core (new_val, "local") ¶Query or set the internal variable that controls whether Octave tries to save all current variables to the file octave-workspace if it receives a terminate signal.
When called from inside a function with the "local" option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
val = octave_core_file_options () ¶old_val = octave_core_file_options (new_val) ¶old_val = octave_core_file_options (new_val, "local") ¶Query or set the internal variable that specifies the options used for saving the workspace data if Octave aborts.
The value of octave_core_file_options should follow the same format
as the options for the save function. The default value is Octave’s
binary format.
When called from inside a function with the "local" option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
See also: crash_dumps_octave_core, octave_core_file_name, octave_core_file_limit.
val = octave_core_file_limit () ¶old_val = octave_core_file_limit (new_val) ¶old_val = octave_core_file_limit (new_val, "local") ¶Query or set the internal variable that specifies the maximum amount of memory that Octave will save when writing a crash dump file.
The limit is measured in kilobytes and is applied to the top-level workspace. The name of the crash dump file is specified by octave_core_file_name.
If octave_core_file_options flags specify a binary format, then octave_core_file_limit will be approximately the maximum size of the file. If a text file format is used, then the file could be much larger than the limit. The default value is -1 (unlimited).
When called from inside a function with the "local" option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.

val = octave_core_file_name () ¶old_val = octave_core_file_name (new_val) ¶old_val = octave_core_file_name (new_val, "local") ¶Query or set the internal variable that specifies the name of the file used for saving data from the top-level workspace if Octave aborts.
The default value is "octave-workspace"
When called from inside a function with the "local" option, the
variable is changed locally for the function and any subroutines it calls.
The original variable value is restored when exiting the function.
