No, the lack of Ctrl-C during computation is itself the feature, which was put in because there was a bug several years ago of how to handle Ctrl-C when executing library code. There are many examples in the bug database with Ctrl-C and multi-threaded code, example here that was labeled "Important": https://savannah.gnu.org/bugs/index.php?47400

In other words: Ctrl-C will work for Octave's code but when it passes execution to an external library routine that's multi-threaded, Ctrl-C is temporarily disabled. This was deemed better than having an interrupt result in a crash.

User cannot break execution of a program using CNTRL+C,
if there is little I/O going on when processing Gigabyte large arrays.

Feature request : interrupting execution should always be possible.
