I have to interface two usb type ordinary webcams to the the matlab and take a video stream of say 40 or 50 frames (or even varying the frames) simultaneously on both the cameras.I want the source code for the following.It would be really helpfull if some one helps me in writing the code for the following.

i dont think matlab is able to handle multi cams, in most vs based
programs, one usb bus is only used for one usb cam, you can try to use
opencv to handle this problem, put 2 usb cam on 2 usb bus then you
should open and use it for stereo vision( i guess this is what you
want to use).

bad news for opencv is resolution seems not adjustable.

Thanks alot 
but i am able to connect two cameras in matlab but i am not able to take simaltaneous video capture but i am able to capture video one camera after the other and also there is a file(vcapg2.dll) for connecting webcams in the Matlab that supports upto 6 webcameras.but still i am not able to use that and program.So if any one could help me out in this problem it would be really helpfull
