Matlab7无法启动的一个解决方法

Matlab7运行出现以下错误：

??? MATLAB was unable to open the
pseudo-tty master device /dev/ptmx. The unix()
and ! commands will not work in this MATLAB
session. Other commands which depend
upon unix() and ! will fail. Please check with
your system administrator and confirm that
this device exists with the proper permissions.

以下是解决方案：
Things to look for:

1. The device /dev/ptmx must exist and be writable.

greg@fess 839$ ls -l /dev/ptmx
crw-rw-rw-   1 root     tty        5,   2 Dec  1 17:28 /dev/ptmx

Use "mknod -m 666 /dev/ptmx c 5 2" to remedy.

2. The directory /dev/pts must exist

greg@fess 840$ ls -ld /dev/pts
drwxr-xr-x   2 root     root            0 Nov 13 09:11 /dev/pts/

Use "mkdir /dev/pts; chmod 755 /dev/pts" to remedy

3. The filesystem type "devpts" must be supported in the kernel

greg@fess 841$ cat /proc/filesystems | grep pts
nodev   devpts

Reconfigure and rebuild your kernel to remedy this.

4. The filesystem /dev/pts of type devpts must be mounted

greg@fess 842$ cat /proc/mounts | grep pts
devpts /dev/pts devpts rw 0 0

Short term remedy: "mount -t devpts devpts /dev/pts"
Long term remedy: put this into a startup script or add it to your /etc/fstab file.
