WHY THIS LIBRARY MIGHT BE USEFUL TO YOU
To do fast matrix vector operations like:
d = A*b + c
or one with the transposed of A like:
d = AT*b + c.
one usually needs to write them in C/FORTRAN 77 (C-tran) code style for performance
reasons. This means that one needs to use several "for loops" in order to do the
products and sums component-wise. Although computationally efficient, this type of programming style is error prone and makes codes lenghtier and hard to be debugged
(see for example http://www.gps.caltech.edu/~walter/FTensor/FTensor.pdf
