Thread Subject: matlab and linux

Anyone running matlab on a linux system? I successfully completed
installation, but when I try to run matlab, I get the following response:
bash: matlab: command not found

it's like it's not recognizing matlab as an executable, and thinks i'm
issuing a command instead. any help appreciated

Err, you could say that. It runs far faster than under 'Doze on the
same hardware, too. :)

No, the issue is that wherever the install put the "matlab" executable
is not in your path. Did you have it create symbolic links
in /usr/local/bin (it asks you during the install)?

You have two options:

1) Find the matlab executable, and run it by specifying the full path, e.g.:

/usr/local/matlab6/bin/matlab -nojvm

2) Put in the symbolic links:

ln -s /usr/local/matlab6/bin/matlab /usr/local/bin/matlab
ln -s /usr/local/matlab6/bin/mex /usr/local/bin/mex

I'd go with 2, although it assumes that /usr/local/bin is in your PATH,
which it most likely is.

As a third possibility, the OP could also add /usr/local/matlab6/bin/ to
the PATH in his or in the system-wide profile, e.g.
export PATH=$PATH:/usr/local/matlab6/bin/
in /etc/profile or ~/.profile, respectively.

It's not the path. I can go into the same directory where the matlabdoc,
matlab and mex executables are and run anything I want except matlab
itself...documentation works, mex works, but for matlab:
bash: matlab: command not found
puzzling! All executables appear blue text, but matlab appears red...i
don't know what this means.

This has to do with the settings of LS_OPTIONS, mine e.g. are -N
--color=tty -T 0 and cause dirs to appear blue and executables red.
Are you sure that the permissions of matlab are ok and that the matlab
you are seeing is not a subdirectory or (possibly stale) link?

Hi,

The problem is probably not related to the path. I don't know
what versions of Matlab and Linux you are using but if you
want to run Matlab 5.3 on a recent Linux distribution you need
to have some old libraries installed to make it work.
You can find a solution for RedHat here

As someone else pointed out, this may have to do with libraries, depeding
on your Linux distro and the version of Matlab. I've also seen that
error when some command in a shell script (which is what that 'matlab'
"executable" is) does not exist.

Please tell us, what

objdump --full-contents --section=.interp ./programmname

says.

If you get something like this:

Contents of section .interp:
 80480f4 2f6c6962 2f6c642d 6c696e75 782e736f /lib/ld-linux.so
 8048104 2e3100 .1.

you have to install shlibs5 from serie 'a' (if you have a suse)

it's obvious but have you tried :

"
chmod a+x matlab

./matlab
"

Hi,
The exact same thing happened to me. What I did was to first go to
/usr/local/bin there I right clicked on the 'matlab' tried opening it. IT gave me error that its a broken link & there is the problem. thats why you cannot run matlab from there.

Solution(that worked for me): go the directory where you installed MATLAB, lets assume its matlabroot. then go to the bin folder i.e
cd /
cd /media/disk/matlabroot/bin (here /media/disk/ is the path for my machine) , you`ll see matlab executable(or whatever its called in LINUX )

try running from there, i.e. in terminal type matlab from this directory, it should run.

If it does then update the 'matlab' link in /usr/local/bin to point to this matlab in /media/disk/matlabroot/bin.

Thanks,
Avinash
