Hermite normal form - Wikipedia

In linear algebra, the Hermite normal form is an analogue of reduced echelon form for matrices over the integers Z. Just as reduced echelon form can be used to solve problems about the solution to the linear system Ax=b where x is in R , the Hermite normal form can solve problems about the solution to the linear system Ax=b where this time x is restricted to have integer coordinates only. Other applications of the Hermite normal form include integer programming, cryptography, and a… WitrynaThe Hermite invariants are characterized in state space terms, and a realization of $\Sigma (s)$ in Hermite canonical form is presented.

In this chapter we develop a systematic method for transforming a matrix A with entries from a field into a special form which is called the echelon form of A. The transformation consists of a sequence of multiplications of A from the left by certain “elementary matrices”. If A is invertible, then its echelon form is the identity ... cheeses lower in sodium
