New Contributers Welcome

Do you think about a new feature in MTEX. Please let us know, but don't hesitate to have a quick look into the internals of MTEX. Maybe your idea is more easily implemented than you might have dreamed of. When developing MTEX we try to keep it as flexible and extensible as possible. So give your ideas a try and become a contributor of MTEX.

21.12.2011 MTEX 3.2.2 Release

This is mainly a bug fix release and follows our new release policy to release frequent updates. It is recommended to everybody to update to this version.

25.09.2011 MTEX 3.2 Release

We are proud to announce MTEX 3.2. This release introduces 3d EBSD data analysis into MTEX. More precisely MTEX is now able to

• import 3d EBSD data from stacked files
• visualize 3d EBSD data by plotting interactive slices through the specimen
• 3d grain detection including topology of 3d grains, i.e. boundaries, neighbouring grains, etc.

Other enhancements include

• misorientation analysis: uncorrelated misorientation distribution, angle distribution, misorienation to mean
• ew syntax for EBSD and grain variables that allows for indexing by phase and region
• better import and export of pole figures, odfs and EBSD data
• automatic centering of a specimen with repsect to its specimen symmetry
• download and import tensors from http://www.materialproperties.org/
• new interfaces for Rigaku, Siemens, Bruker and many other X-ray devices and formats
• support for rank three tensors, i.e, for piezo electricity tensors

For more details have a look at the ChangeLog.
