Dear vinay

my purpose is to give a signal from matlab to an exterior system; so can i use national instruments for this? Please name one of the simple type of such instrument if it possible. Tanx

do you mean image processing? you just need the image processing toolbox in matlab.

If you are talking image acquisition, then you would need a daq card (try National Instruments or something similar). But you would still need the toolbox within matlab to process the data.

If you are low on funds, and your computer has a serial or parallel port, you could alternatively communicate via those ports; depending obviously on what you are trying to communicate to and whether that device has a serial port/parallel port communication capability. There are several companies with DAQ hardware other than NI, though that is the best established one among them. Check with Matlab to see what all companies it can talk to; I think NI has student kits available (atleast for Labview, not sure if they have hardware on discount). Hope that helps....
