CTRL-Z in Matlab 2007a on Intel Mac

Sam Waldman — Thu, 28 Jun 2007 12:31:27 -0400

Hi Folks,

I run Matlab on a variety of platforms both locally and remotely. I
use the command line interface almost exclusively (as do most of my
colleagues) because I often work on large compute clusters located in
big rooms far away from my desk. I have recently upgraded to a Core
Two Duo Mac and Matlab 2007a. I find that "CTRL-Z" doesn't suspend
the MATLAB session and go to the command line as I believe it should.
Is there a work around for this or is this a new feature of the
Macification of Matlab?

Thanks in advance for your help,

sam

Play with "stty -a" in your terminal (before launching MATLAB) and see if
^Z is still bound to "susp". If MAC supports such a thing. Anyway I
suspect a terminal/shell issue rather than a MATLAB issue.

But...

In recent years ML has moved away from being a console app, providing
its own window and CLI. If you choose to run "-nojvm" (as all sane
people would), the behaviour of CTRL-Z is your choice.

Thanks Peter and Steve,

My terminal "susp" is still bound to "^Z" as it should be. My
previous install of Matlab on a G4 Mac had ^Z work fine (sorry, I
don't remember which version). Other applications work fine with ^Z
and the "feature" persists with different terminals and emulation,
ie. xterm, vt100, or Terminal.

Cheers,
sam

In that case I bet the "screen" program will let you work around this
for now.
