The OIM Matrix™ from EDAX is a software package provided as an option with OIM Analysis™. This enables users to simulate EBSD patterns depending on the physics of the dynamical diffraction of electrons.
Compared to conventional kinematic diffraction-based approaches, this method offers a highly precise explanation of the electron interaction behavior inside a sample and produces more evident pattern simulations. Such simulated patterns could be more quickly and accurately compared with experimentally gathered EBSD patterns.

OIM Matrix can make a library of EBSD patterns for all crystallographic orientations for a provided material. Then, experimental patterns can be compared and paired with the best fitting pattern in the library in a method known as Dictionary Indexing, developed for EBSD by the group of Professor Marc De Graef at Carnegie Mellon University.
Dictionary Indexing increases indexing success rates over standard Hough-based indexing methods. Within OIM Analysis™, the first-class software platform for the analysis of EBSD data, Dictionary Indexing could be integrated along with partitioning functionality and other indexing tools for effective indexing enhancements and improved whole data quality.
