How do I call Matlab in a script on Windows?
- by Benjamin Oakes
I'm working on a project that uses several languages:
SQL for querying a database
Perl/Ruby for quick-and-dirty processing of the data from the database and some other bookkeeping
Matlab for matrix-oriented computations
Various statistics languages (SAS/R/SPSS) for processing the Matlab output
Each language fits its niche well and we already have a fair amount of code in each. Right now, there's a lot of manual work to run all these steps that would be much better scripted. I've already done this on Linux, and it works relatively well.
On Linux:
matlab -nosplash -nodesktop -r "command"
or
echo "command" | matlab -nosplash -nodesktop
...opens Matlab in a "command line" mode. (That is, no windows are created -- it just reads from STDIN, executes, and outputs to STDOUT/STDERR.) My problem is that on Windows (XP and 7), this same code opens up a window and doesn't read from / write to the command line. It just stares me blankly in the face, totally ignoring STDIN and STDOUT.
How can I script running Matlab commands on Windows? I basically want something that will do:
ruby database_query.rb
perl legacy_code.pl
ruby other_stuff.rb
matlab processing_step_1.m
matlab processing_step_2.m
# etc, etc.
I've found out that Matlab has an -automation flag on Windows to start an "automation server". That sounds like overkill for my purposes, and I'd like something that works on both platforms.
What options do I have for automating Matlab in this workflow?
