reduces a matrix to Hermite normal form
where matrix is a numeric matrix or literal.
The HERMITE function uses elementary row operations to reduce a matrix to Hermite normal form. For square matrices this normal form is upper triangular and idempotent.
If the argument is square and nonsingular, the result is the identity matrix. In general the result satisfies the following four conditions (Graybill 1969, p. 120):
a={3 6 9, 1 2 5, 2 4 10}; h=hermite(a);These statements produce the following output:
H 3 rows 3 cols (numeric) 1 2 0 0 0 0 0 0 1If the argument is a square matrix, then the Hermite normal form can be transformed into the row echelon form by rearranging rows in which all values are 0.
