Upgrading from an Earlier Release
2-29
no longer produces any output. Prior to Release 12, a background command
sent output to the command window.
If you need to see the output from a command, either do not make the command
a background command (i.e., remove the
&), or run the background command
in a separate xterm. To start another xterm, issue the following command.
! xterm &
In Release 12, foreground functions (i.e., nonbackground functions) send their
output to the diary, if the
diary function has been issued. The output is also
displayed in the command window (prior to Release 12, foreground function
output was only displayed in the command window).
matlab_helper Process
To make the ! and unix commands operate more efficiently, in Release 12
MATLAB creates a secondary process, called
matlab_helper, at startup.
This
matlab_helper contains those elements of MATLAB necessary to run the
! and unix commands.
Graphics Issue
MATLAB No Longer Supports Terminal Mode
MATLAB no longer runs on nongraphics computer terminals.
