IMAT™, the Interface between MATLAB, Analysis, and Test, is a toolbox that allows MATLAB to exchange data with a variety of software including I-deas, Nastran, FEMAP, and Abaqus, as well as other software packages. It provides a powerful means for manipulating test and analysis data in MATLAB while preserving data attributes. IMAT's capabilities are extended even further through several extensions that are grouped according to the type of functionality they contain. All of the capabilities and their documentation are included in the IMAT package, but the extended functionality requires an additional license. Please contact us for more information.
IMAT+FEA allows the user to interface with several different analysis packages including Nastran, FEMAP, and Abaqus. In most cases bi-directional support is provided. IMAT+FEA functions are marked with a +FEA next to the documentation. You can read more about IMAT+FEA here.
IMAT+Modal provides functionality geared toward the modal test engineer. IMAT+Modal provides capabilities for generating Test Analysis Models (TAMs) in Nastran, optimal accelerometer selection using a genetic algorithm, and many routines for processing modal test data. IMAT+Modal functions are marked with a +Modal next to the documentation. You can read more about IMAT+Modal here.
IMAT+Signal extends IMAT by providing functionality that facilitates signal processing, both with stationary and rotating signals. In addition to command-line functions, SPFRF is a GUI that provide an easy-to-use interface for processing stationary signals. RTK is a GUI that encapsulates the process of obtaining response characteristics and finding insights into the mechanics of rotating events. It applies the Vold-Kalman filter technique to order-tracking of rotational events. IMAT+Signal functions are marked with a +Signal next to the documentation. You can read more about IMAT+Signal here.
In MATLAB, you can type "help function" on any IMAT function to get a description of the syntax and usage of that function. If you type "help imat", you will get a list of most available functions.
Please review the Compatibility Considerations for any compatibility changes between releases.
