Rationale

I have enjoyed a considerable boost to my own work fromseveral open source projects over the years, and Ialso have made the libraries and toolkits that I designed myselfavailable to others. Open source works!

The material on this page is intended to be aneducational resource for undergraduate or graduate coursesof finite element analysis, for mechanical, chemical, civil, and other engineeringstudents. You will find here asoftware toolkit for Matlab. The software is available as open source.

Bymaking theseresources available to everyone, I'm hoping to beable to collect feedback and suggestions that will enhance the usefulness of this material for everyone.

Thesoftware is protected by theGNUGeneral Public License.

For the software, any ideas, suggestions, and design insights are welcome.I will decide whether I'm going to include any modifications in my version of the toolkit,which is going to be available from this web site. You, on the other hand,have the freedom to work any modifications into your own version of the toolkit.
