Troubleshooting Matrox Devices

Device Discovery

If you are having trouble using the Image Acquisition Toolbox™ software with a supported Matrox® frame grabber, try the following:

  1. Install the Image Acquisition Toolbox Support Package for Matrox Hardware.

    Starting with version R2014a, each adaptor is available separately through MATLAB® Add-Ons. See Image Acquisition Support Packages for Hardware Adaptors for information about installing the adaptors.

  2. Install the Matrox Imaging Library (MIL) separately and verify that it is the supported version for your MATLAB release. Check the supported versions in the Third-Party Requirements section on Matrox Frame Grabber Support from Image Acquisition Toolbox. If you discover that you are using an unsupported driver version, visit the Matrox website to download the correct drivers.

    Note that the matroxcam and matroxlist functions that are available with the matroxcam object starting in release R2015a work with MIL or MIL-Lite 10.x only. Use of the matrox adaptor with the videoinput object can use either MIL 9 or 10.

    Find out the driver version you are using on your system. To learn how to get this information, see Determining the Driver Version for Matrox Devices.

  3. Verify that you are using supported image acquisition hardware and that it is functioning properly. See a list of supported Matrox frame grabbers on Matrox Frame Grabber Support from Image Acquisition Toolbox.

    For Matrox devices, run the application that came with your hardware, Matrox Intellicam, and verify that you can receive live video.

  4. Make sure no other application is accessing the frame grabber.


There is no difference between MIL and MIL-Lite software inside of MATLAB. They both work with Matrox Imaging devices.

Determining the Driver Version for Matrox Devices

To determine the Matrox Imaging Library version you are using, run the Matrox MIL Configuration utility. You can access this software through the Windows® Start button.

Select Start > Programs > Matrox Imaging Products > MIL Configuration.

The software version is listed on the Information tab.


As of version R2014b, the Image Acquisition Toolbox supports MIL 10, and that is the recommended version to use.
