Hermite Matrix

Saw your very appropriate query of nearly a year ago on the relevance of reduced row-echelon form to upper triangular matrices, in Talk: row-echelon matrix. Indeed, the Hermite matrix was defined incorrectly: when lower rows of zeros are appended to a reduced row-echelon matrix, one creates a very special upper triangular matrix: the Hermite matrix. The difference between it and the identity matrix, I-H, is a matrix whose columns are the solution set of the homogenous set of linear equations Ax=0. This is only one way of solving this set of equations, but it's attractive because the proof that it is a solution can be given in the algorithm. I've left it to mathematicians to correct the article. Geologist (talk) 01:24, 17 March 2008 (UTC)
