Questions[matlab](ubuntu)

I need Cuda 10.1, for PyTorch, TensorFlow, and MatLab. They don't support Cuda 11. I also need steam to play games. Is there any way I can use Cuda's parallel processing while able to play games on steam. Please help.

Steam requires libnvidia-gl-440:i386.

The following packages have unmet dependencies:
libnvidia-gl-440:i386 : Depends: libnvidia-gl-450:i386 but it is not going to be installed

But installing libnvidia-gl-450:i386, says:

The following packages will be REMOVED:
cuda-10-1 cuda-demo-suite-10-1 cuda-drivers cuda-drivers-450 cuda-runtime-10-1 libnvidia-compute-450 libnvidia-decode-450 libnvidia-encode-450 libnvidia-gl-450 libnvidia-ifr1-450 nvidia-compute-utils-450 nvidia-driver-450 nvidia-utils-450

Tried links: Steam won't launch on Ubuntu 18.04 Steam not working on Ubuntu 20.04 but didn't help with Cuda and steam both at the same time.

Edit:

It's not only with steam, it won't allow me to use any other 32-bit application. Installing libnvidia-gl-450:i386 asks to remove Cuda 10.1 which I can not.

I am looking for a way to run Cuda, as well as use all the 32-bit arch applications. As stated above Matlab, Pytorch, TensorFlow do not support Cuda 11.

I recently installed Matlab R2013a and it is working fine, however the only way I can start it is by running /usr/local/MATLAB/R2013a/bin/matlab in the terminal. If I type in matlab it says command not found, and I can't seem to get an icon in the side-bar launcher. How can I make it so I can run from the command matlab or from a launcher?

Edit: I have created a link so I can launch it by typing matlab in the terminal. I still can't get the unity icon launcher working though. I managed to create an icon via a matlab.desktop file in /usr/share/applications. When I click it, it launches Matlab, but after the initial loading screen Matlab shuts down instead of launching the application. It works through the terminal though. My matlab.desktop file is:

[Desktop Entry]
Type=Application
Name=Matlab
Comment=Matlab R2013a
Icon=/usr/share/icons/Matlab.png
Exec=/usr/local/MATLAB/R2013a/bin/matlab
Categories=Office
Terminal=false`

I'm trying to install a Matlab R2011a launcher for Unity in Ubuntu 12.04. I've tried this guide (although I know it's for 11.10 and mentions that even 11.10 is an unsupported OS for Matlab R2011a) but without any satisfactory solution.

This is my launcher file, /usr/share/applications/matlab.desktop:

#!/usr/bin/env xdg-open
[Desktop Entry]
Type=Application
Icon=/usr/share/icons/matlab.png
Name=MATLAB R2011a
Comment=Start MATLAB - The Language of Technical Computing
Exec=matlab -desktop
Categories=Development;

I open the dash panel and search for "matlab". This launcher is found among applications. I click it, and Matlab's splash screen shows up, but when it disappears the program doesn't start. (I've verified with htop that no matlab-processes are running in the background either.)

If I add

Terminal=true

to the launcher file, the program starts OK, and opens a terminal as well as Matlab. However, both the terminal and Matlab itself show up in the Launcher area, with the Matlab icon, so it looks like I have two Matlab instances running when really it's only one. (Actually, they show up as two different programs, and not just two instances of the same - the icons are independent, not grouped together.)

This is definitely not optimal. I had hoped to create a launcher I can lock to the launcher area, and then that same icon will be the icon for the active Matlab instance when the program is running.

How do I create a launcher for Matlab that works as expected?

Update: I was apparently a bit unclear on my symptoms, I'll try to clarify a little. I've also tried some suggestions from the answers, and further investigated what happens. My current setup (a launcher file with Terminal=true and Exec=matlab -desktop -nosplash &) renders the following behavior:

1. I open Dash by pressing the Windows key on my laptop, and search for "matlab". It finds the launcher named "MATLAB R2011a". I click it.
2. A terminal window opens, using the icon I referred to in the launcher file. Almost immediately, MATLAB's splash screen also opens, using the same icon (and thus being grouped with the terminal window in the launcher).
3. The splash screen disappears and, so does one of the icons in the launcher. The MATLAB desktop environment opens, using a different version of the icon which is displayed next to the icon for the terminal window (not grouped with it).

I can lock the terminal window's icon to the launcher and successfully start MATLAB by clicking it, but it doesn't feel optimal that I start the program with one icon, and switch to it with another. I've also tried the following:

• Exec without the ampersand & in the launcher command, but it didn't make a difference.
• Executing matlab -nosplash manually from a terminal still shows the splash screen. (What, then, does the nosplash option really do?)

I'd like to know the equivalents of Mathematica, Maple, or MATLAB on Ubuntu, since both are costly.
