M is a free software for symbolic calculations developped
by Peter Overmann in Heidelberg. It seems to me that it is
very powerfull. Although it is not as fast as
**FORM**, it is
a very powerfull tool for High Energy Physics.
You can find this software
**HERE**.

In the following, you can find a few examples of what one can do with this software. This examples corresponds to tests that I performed after 1 day learning how to use it.

- Simple benchmark
- Traces of gamma matrices and manipulations
- Another file for computing traces of products of Dirac matrices
- idem with the implementation of the multilinearity of the scalar product and the Levi-Civita pseudo tensor
- Commutators of non-commutative symbols
- Difference of two sets
- Simplification of expressions with some tensors contracted (Library routine which rename dummy indices)
- Calculation of the Higgs Kinetic terms
