matlab - script file for invoking MATLABSYNOPSIS
matlab [-h | -help] | [-n] [[-c licensefile] -display hostname:display] [-debug] [-Debugger [options]]DESCRIPTION
matlab is a Bourne shell script that starts the MATLAB executable (note lower case matlab refers here to the script and upper case MATLAB refers to the application program). Before actually initiating the execution of MATLAB, this script configures the runtime environment by: o Determining the MATLAB root directory o Determining the host machine architecture o Processing any options specified o Reading the MATLAB startup file, .matlab5rc.sh o Setting MATLAB environment variables There are two ways in which you can control the way the matlab script works: o By specifying command-line options o By assigning values in the MATLAB startup file, .matlab5rc.sh The file .matlab5rc.sh is a shell script that contains definitions for a number of variables that the matlab script uses. These variables are defined within the matlab script, but can be redefined in .matlab5rc.sh. When called, matlab looks for the first occurance of .matlab5rc.sh in the current directory, in the $HOME directory, and in the matlab/bin directory (where the template version of .matlab5rc.sh is located). You can edit the template file to redefine information used by the matlab script. You can copy the edited version to your current or home directory if you do not want your changes applied system wide. Ensure that you edit the section that applies to your machine architecture. The .matlab5rc.sh file defines the following variables: ______________________________________________________ The FLEXlm license file. TOOLBOX Path to the $MATLAB/toolbox directory MATLABPATH The MATLAB search path. The initial path created at install time is stored in $MATLAB/toolbox/local/pathdef.m. XAPPLRESDIR The X application resource directory $MATLAB/app-defaults XKEYSYMDB The X keysym database file $MATLAB/app-defaults/XKeysymDB SHELL The shell to use when "!" is issued in MATLAB ------------------------------------------------------- The matlab script determines the path of the MATLAB root directory by looking up the directory tree from the matlab/bin directory (where the matlab script is located). The $MATLAB variable is then used to locate all files within the MATLAB directory tree. You can change the definition of $MATLAB, if for example, you want to run a different version of MATLAB or if, for some reason, the path determined by the matlab script is not correct (this may happen when certain types of automounting schemes are used by your system). $AUTOMOUNT_MAP is used to modify the MATLAB root directory path. Whatever pathname that is assigned to $AUTOMOUNT_MAP is deleted from the front for the MATLAB root path. (It is unlikely that you will need to use this option.) See the comments in the .matlab5rc.sh file for more explanation on these variables.OPTIONS
-h, -help This option shows matlab command usage. MATLAB is not started when you specify this option. -n This option causes matlab to display the values of the environment variables used by MATLAB. MATLAB is not started when you specify this option. -c licensefile Sets the value of the LM_LICENSE_FILE variable to licensefile. This setting supersedes values specified in .matlab5rc.sh and the default values defined within the matlab script. license.dat.DEMO.* files in the matlab/etc directory. -display hostname:display The X display used for MATLAB output. For example, matlab -display falstaff:0 cause MATLAB output to be displayed on the host named falstaff. The value specified with this option supersedes the value of the DISPLAY environment variable and the display variable defined in .matlab5rc.sh. -debug Provides debugging information, especially for X- based problems. Note that your should use this option only in conjunction with a Technical Support Representative from The MathWorks, Inc. -Ddebugger options Start MATLAB with the specified debugger (e.g., dbx, xdb, gdb, ups, etc.). Any debugger options you want to use should be specified in options. Using the -D options sets the environment variable: MATLAB_DEBUG=debugger Note that for certain debuggers, such as gdb, the SHELL environment variable is always set to /bin/sh. This option is useful for using a debugger on MEX-files, which are subroutines linked to MATLAB. You should build the MEX-file using the -g option. (See the mex manual page for information on building MEX-files. See the MATLAB Application Program Interface Guide for information on debugging MEX-files).FURTHER INFORMATION
If you have a Web browser like Netscape you can easily access online documentation for MATLAB. If you are at the Unix shell prompt then invoke the matlabdoc command, for example, $ matlabdoc Go to the link MATLAB Help Desk. The matlabdoc command is accessable in the same may as the matlab and mex commands. If you are at the MATLAB prompt use the helpdesk command, for example >> helpdesk There are a number of manuals. See the MATLAB Installation Guide for information on installing MATLAB. See the GettingSEE ALSO
