Matlab installation

**mmsltni** · October 22nd, 2011

Hi everybody.
I have installed matlab but I don't install it in default destination.After that I create Matlab luncher by

Code:

sudo wget http://upload.wikimedia.org/wikipedia/commons/2/21/Matlab_Logo.png -O /usr/share/icons/matlab.png

and

Code:

sudo wget 'https://help.ubuntu.com/community/MATLAB?action=AttachFile&do=get&target=matlab-r2010b.desktop' -O /usr/share/applications/matlab.desktop

Now when I lunch it by opening it at usr/share/application It can't run and says :

HTML Code:

Details: Failed to execute child process "matlab" (No such file or directory

What can I do?

And second,Is there any way to install Orcad in linux?Is it possible to install it by virtual box or is there any version of that for Linux?

Thanks.

Hi mmsltni,

There is also octave that can do quite a lot of the matlab stuff.

Code:

sudo apt-get install octave

Maybe you will be prompted to select one of many versions, e.g.

Code:

sudo apt-get install octave3.2

Have fun finding out

Why do you choose to avoid the default destination for Matlab? You just create problems for yourself by doing so.

OrCad is not available to run natively on Linux. You can try it with wine, and it should certainly work on a Windows VM

Since you've picked a non-default location, edit /usr/share/applications/matlab.desktop and provide the path for the matlab executable.

I don't have enough space in default dir.
Olle Wiklund,I know octave but I get use to work with matlab...

The simplest solution would be to symlink to the executable (this way you would also be able to launch Matlab from the terminal by typing "matlab").

This requires sudo privileges, so be sure to either trust me or check what these commands do before using them. You can do all this without the terminal, but this way it's easier.

Code:

sudo ln -s <path-to-your-matlab-binary-here> /usr/bin/matlab

Then you have to edit the launcher. All launchers are found in the /usr/share/applications/ directory and end in .desktop. You need sudo privileges to edit things here. Remeber to use gksudo instead of sudo when invoking graphical applications.

Code:

gksudo gedit <name-of-the-launcher>

In there, you'll find a line that starts with exec=. Change whatever is behind that to matlab -desktop. With the -desktop option, Matlab doesn't require an open and unusable terminal all the time.

Good luck!

P.S.: Step 2 will only work if you did step 1 as well.
