Hi F. B., Thank you so much for your work! That'd be great to have. I have seen that a lot of work has been starting on the tensor analysis (here<https://github.com/mnick/scikit-tensor>for example), but it'd be nice to have a symbolic tool especially in this field. I use to write over 50+ pages of derivation in continuum mechanics and I think this will be really a must-have to free mechanical engineers :)
Looking forward to the new features! -Shawn On Friday, October 4, 2013 1:47:49 AM UTC-4, F.
