I will be accessing my work computer from home and i need to make some graphs , ( dont have matlab in my home computer) but i do in my work computer. also i am using linux
i was wondering does anybody know how to do that 1: run matlab in the work computer while accessing form home 2 if i have a script . can i use it and how do i run it.
Any help will be appreciated thank you

One of the common remote graphics protocols that is usable on Linux and Windows is named VNC.
Unfortunately I have not been able to get VNC to work properly with MATLAB (or some other programs.) The difficulty I encounter is that any JAVA component does not render in to the VNC-relayed area. No graphs, no desktop.
What kind of system are you using at home? It may have X (Linux has it; Mac OS has it but you might have to start it up first; you can get commercial X for MS Windows from Hummingbird; you can get free X for MS Windows in a unix emulation layer such as AT&T's uwin). If you have X and can get it set up properly, then ssh -X (Unix-style) or putty (Windows) should be able to allow you to do a remote login to the system at work (firewalls permitting) and to display the graphics to your desktop. Depending on your line speed and the latency to your workplace, the result might be somewhere between "sluggish but okay" and "I could have walked to work, done everything, and walked back before it rendered the first screen!".
I work less than 5 km from my office, but my office's internet connection goes through a private network to a central control point more than 1500 km away; the resulting latency makes it take about 4 minutes per frame to render. My blood pressure can't deal with that.
VNC works much much faster than remote X except perhaps in high-speed local networks; unfortunate that VNC will not work with Java for me.
I assume your work machine is on a network. Are you able to use a virtual private network (VPN) to connect your home machine to that network? That is probably the most common practice these days.
There is also something called "remote desktop protocol" that you can use. I've only done it from a PC, but I think you can do it from Unix as well.
Also, although I have not done it, you can run MATLAB remotely via smart phone app now.
I am able to access my work computer form hoem using ssh and i did try opening matlab but it said that i can see the dislay. so how do i use matlab if i cannot see it , is there any code or command that i can use to run script and get plots
How I remotely connect to a Linux machine from a Windows machine over VPN. I am assuming your home machine is Windows -- but these steps are the same for any arbitrary VNC client, be it on Windows, Linux or Mac.
I like using VNC versus forwarding X, as the VNC method keeps your session running even when you lose network connectivity, which can and does happen for any number of reasons. It's also faster and more responsive, for the most part, for the reasons Walter already mentioned. I've also found that it can help immensely to play around with the VNC settings and try a couple of different VNC clients -- some behave better than others connecting to some systems.
A word of caution, though -- VNC is not the most secure protocol in the world. If you work for a company/institution that is extremely sensitive about network security, it would behoove you to ask for the "proper" way to do this, as there are ways to make things more secure, but they require more setup.
Also if you run long sessions from Linux/UNIX/(Mac?) over network you have to guard yourself from time-outs that close the connection. Do this by running matlab from inside 'screen'. Then you can dettach and reattach the matlab session without losing it.
