Iinterface between MATLAB and Vizard

[suraj]

I am new while working with vizard. but i have experience in working with matlab.

In my application i want to interface output generated by matlab with the vizard environment. Precisely, i want to access physiological signal such as heart rate in and process that in matlab to generate an output. e.g. , if the heart beat rate is above 85 bpm i want to generate an output of one(1) then i want to get this digit one(1) in vizard environment which will initiate a sequence of activity in vizard environment.

I have gone through the conversation threads on the vizard forum but they do not answer my question.

Maybe pymat can be used. i will use win32 system with latest version of vizard "lite version". can someone please show me a way or show your experience while using pymat or any other plug-ins.

Thanks,
Suraj

If you can send data from matlab over the network than you can get this data using Vizard's networking commands.

This is really a good advice. Thank you for the reply.

1.What if i want to use same system(laptop) for matlab and vizard.

2.And If i use "C" drive for matlab and "D" drive for vizard will this help for speed performance of the system?

Thank you in advance!

1. That should be fine. You can send/receive data to another application on the same machine. When you create the network connection specify 'localhost'.

2. I don't think so.

Thanks!
One more thing,I found that "Pymat" can be used to interface between matlab and Python and because vizard is based Python so is this fine?

I have installed python3.2.3 and Numpy3.2 and i havd matlab 2009ra installed as this site "http://pymat.sourceforge.net/" says but could not install Pymat (could not follow the step 5 and 6 of "How do I build it?"). i also tried to download Pymat from site"http://claymore.engineer.gvsu.edu/~steriana/Python/" but got it's 2.2 version which is not supported in Python3.2 ver.I downloaded Pymat form other site in which it has "setup.py" i don't know how to get it worked.
I want to know how to install Pymat for the "Python win32 version 3.2.3". I tried the given example from"http://claymore.engineer.gvsu.edu/~steriana/Python/pymat.html" but did not worked.

Sorry for the long reply.

Thanks,

Vizard 4 uses Python 2.7 so it won't work with PyMat.

[suraj]

will the Python 2.2 work? Because i have Pymat 2.2 so i can install Python 2.2.

[suraj]

Can i use Python 2.2 with vizard? If so to use Pymat i need Python2.2, Numpy 2.2 and Pymat 2.2, means all of same version. I have Python 2.2 and Pymat 2.2 but i did not get Numpy for Python 2.2 to use.Pymat 2.2 is the latest one which i got. can you help me to use Pymat with any version of matlab?
