how to remove an Image Acquisition Toolbox adaptor?

If I register an adaptor with the image acquisition toolbox, then I will not be able to register another adaptor with the same name.

I am writing my own adaptor and I need to test it. I don't want to give a new name for the same adaptor everytime. So, how do I unstall an adaptor in Matlab?

When you register an adaptor, what you are really registering is the
file location, so if you're just compiling a new version of the adaptor
but keeping the location the same, you don't need to worry about
re-registering it.

If really do want to unregister an adaptor, you can do the following:

>> imaqregister('myadaptor.dll', 'unregister');

Also, if you want to keep MATLAB open during testing and recompilation,
you can call IMAQRESET before compilation so that the toolbox releases
the adaptor DLL. The adaptor DLL will then be reloaded the next time
you call IMAQHWINFO or VIDEOINPUT (for that adaptor).
