Using Mathlab with Ruby

Hi,

I am very new to Matlab and I don't know about all it's possibilities. I am analysing the possibilities of using Matlab externally from another program. Right now, our users are sending use a data set that we pass through a Matlab program. We are doing this manually, but we would liek to automatize the process.

I will build a website backend in Ruby and on the web interface, the user can upload a data file which I would like to pass to the Mathlab program via my Ruby programm and save the results.

I have seen that one can start Matlab as a Automation Server. Could I use this like an API to do what I want ?

Any help would be very useful.

I asked a similar question a couple of weeks ago and haven't managed to do much with it.

You can also compile a matlab program into an executable, and interact with that via system calls. - Though it effectively starts matlab each time, before executing the program.

Hi, thanks for your answer. This means that even if I create an matlab executable on my server, I still need to install the Matlab on that same server ?

I also run into this doc. I appears I could start matlab as an Automation Server and use javascript to communicate...

I did not test it yet, though :-o

Thanks

No. It means you need to install the compiler runtimes on the system you want to run the compiled code.

If you then compile a program (a function), and run it on that system, it'll take a long while loading stuff in before it runs the function you want it to run.

As for the automation server - I'm pretty certain that the server will need matlab installed.
