The patch works fine. I added the bug number to the commit message and checked it in on the development branch here (https://hg.savannah.gnu.org/hgweb/octave/rev/3c9134d90d6e).

Marking as fixed and closing report.

The workspace is explicitly updated by 'clear' in variables.cc. Removing 'octave_link::set_workspace' in 'clear' should already do the trick (see attached patch).

If the following is saved as a script file, testscript.m,

then the script runs for 5 seconds, during which the GUI workspace panel stays blank. After the script finishes completely, the workspace panel shows i, x, and y.

If the script is changed to the following,

the 'clear' command causes the GUI workspace panel to be updated while the script is executing, showing the value of i iterating from 1 to 25.

I don't think using the 'clear' command in a user script should trigger the workspace panel to update unexpectedly. Normally the workspace only updates when control is returned to the user, when a script or function call returns to the prompt, when the debugger is activated, or when an input function such as 'input' or 'kbhit' is called.
