And are you using the 32 bit or 64 bit MATLAB?

IVI-COM is not supported on 64-bit platform. However, if the driver installs both the 32 as well as 64 bit, then you should be able to use the 32-bit driver from 32-bit MATLAB.

The difference between the IVI-C and IVI-COM is explained by pacificmindworks.com in this PDF document.

I installed version 1.1.8 of the IVI driver for the instrument you listed. That driver comes along with MATLAB driver and is automatically installed. You might want to update your driver if it is not the latest one.

There is also an example that is shipped with the driver that shows how to use the driver, once installed. Here's a sample code:

    % Create driver instance
    driver = instrument.driver.AgInfiniiVision();
    % Edit resource and options as needed.  
    % Resource is ignored if option     Simulate=true
    % resourceDesc = 'TCPIP0::<host_name or IP addr>::INSTR';
    resourceDesc = 'GPIB0::7::INSTR';
    initOptions = 'QueryInstrStatus=true, Simulate=true, DriverSetup= Model=, Trace=false';      
    idquery = true;
    reset   = true;
    driver.Initialize(resourceDesc, idquery, reset, initOptions);
    disp('Driver Initialized');
