text: % 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)
