MATLAB: Can I not see what I am typing in the terminal after I exit MATLAB 7.10 (R2010a) which was started with ‘-nodesktop’ or ‘-nojvm’ flag under bash

gnome-terminalinvisiblekonsoleMATLABresetrxvtsttyxterm

After running MATLAB with the '-nodesktop' or '-nojvm' flags under the bash shell, the terminal window no longer echoes keyboard input.

For example:

1. Start bash

     bash

2. Start MATLAB without the desktop

    matlab -nodesktop

3. Run any numeric computation and exit:

      ones(10,1) * ones(1,10);
      exit

4. At this point, the terminal will not display any keyboard input.

This enhancement has been incorporated in Release 2012a (R2012a). For previous product releases, read below for any possible workarounds:

This is a bug in MATLAB 7.10 (R2010a) on Linux and Mac.

There are two possible workarounds:

1. Run MATLAB under a different shell. For example, neither tcsh or zsh have this issue.

2. Reset the terminal after MATLAB exits by running RESET command in the terminal window:

     reset

MATLAB: Do I receive an error about gcc version when executing a MEX-file or an executable generated by MATLAB Compiler on Linux

This bug has been fixed in Release 2007a (R2007a). For previous product releases, read below for any possible workarounds:

This error may occur when you use MATLAB or MATLAB Compiler in combination with GNU gcc 3.3.x, with gcc 3.2.3 that is distributed by Red Hat, or with another unsupported version of gcc. For the list of supported compilers, consult the following document:

http://www.mathworks.com/support/compilers/current_release/

See the related solution to compile and install a fully compatible GNU gcc. While installing the supported version of gcc is strongly recommended, some of our customers have reported the following workarounds are successful. These workarounds have not been tested and are not supported by MathWorks.

Workaround 1:

Before starting MATLAB (if executing a MEX-file) or before executing a file generated by MATLAB Compiler, set the LD_PRELOAD environment variable to /lib/libgcc_s.so.1

For bash users:

 export LD_PRELOAD=/lib/libgcc_s.so.1

For csh users:

 setenv LD_PRELOAD /lib/libgcc_s.so.1

Workaround 2:

Another workaround is to replace some library files in the MATLAB installation with the corresponding libraries from the version of GCC you are using. Be sure to create backup copies of any libraries you replace, since you may have errors in MATLAB after replacing the libraries. For example in MATLAB 7.1 (R14SP3) you could replace the following files:

libg2c.so.0.0.0 
libgcc_s.so.1 
libstdc++.so.5.0.3

and the symbolic links associated with these files with newer libraries from your gcc release. The files to be replaced are in the following directory:

$MATLABROOT/sys/os/$ARCH

(where $MATLABROOT is the MATLAB root directory on your machine, as returned by typing:

matlabroot

at the MATLAB command prompt and $ARCH is your architecture "glnx86" for 32-bit Linux and "glnxa64" for 64-bit Linux.)

MATLAB: Is the MATLAB startup option ‘-r’ not working properly on C UNIX Shell

This is the expected behavior because when MATLAB has been started without the desktop, it expects to be able to read from standart input ('stdin'), however, when you start it in the background, it cannot read from 'stdin' and the process will be stopped.

As a workaround, you can create a text file which includes the commands you want to execute and use input redirection operator "<" instead of "-r" option. For example, assuming the file "foo.txt" includes the lines

 ver;
 exit;

you can execute the command

 matlab -nodisplay -nodesktop -nojvm -nosplash <foo.txt >out.txt &

As another workaround, you can write a shell script which automates the process.
