% BTF ordering toolbox: % % Primary functions: % % btf - permute a square sparse matrix into upper block triangular form % maxtrans - permute the columns of a sparse matrix so it has a zero-free diagonal % strongcomp - symmetric permutation to upper block triangular form % % Other: % btf_install - compile and install BTF for use in MATLAB. % btf_demo - demo for BTF % drawbtf - plot the BTF form of a matrix % btf_make - compile BTF for use in MATLAB % % Example: % q = maxtrans (A) % [p,q,r] = btf (A) % [p,r] = strongcomp (A) % BTF, Copyright (c) 2004-2022, University of Florida.
