Simulink .mdl files are in simple ascii text format. MDL stands for Model File Format. It contains keywords and parameter-value pairs that describe the model. The file describes model components in hierarchical order. There are quite a few fellows that have worked on parsing .mdl format. This is an example using python: http://www.fauskes.net/nb/parsing-simulink/ Scrolling all the posts in the above page I could get lots of info. Another example in Java: http://conqat.cs.tum.edu/index.php/Simulink_Library Agostino Quoting b mills <bri...@in...>: > I've been using modified Aerosim xml parsers to import JSBSim config > files into Matlab for several years now.
