Reid alg approximate minimum degree ordering file linalg/amd/amdhat.f for approximate minimum degree ordering of a sparse symmetric matrix , (Gilbert, Moler, and Schreiber bound on external degree) by Timothy A. Davis, Patrick Amestoy, Iain S. Duff, and John K. Reid alg approximate minimum degree ordering file linalg/amd/amdpre.f for the amdpre routine is a preprocessor to amdbar. It removes dense rows , and columns from the matrix prior to ordering by amdbar and can thus , be much faster than amdbar alone. size 164k by Timothy A. Davis and Joseph L.
