function p = metis (A, mode) %#ok
%METIS nested dissection ordering via METIS_NodeND.
%
% Example:
% p = metis(A) returns p such chol(A(p,p)) is typically sparser than
% chol(A). Uses tril(A) and assumes A is symmetric.
% p = metis(A,'sym') the same as p=metis(A).
% p = metis(A,'col') returns p so that chol(A(:,p)'*A(:,p)) is typically
% sparser than chol(A'*A).
% p = metis(A,'row') returns p so that chol(A(p,:)*A(p,:)') is typically
% sparser than chol(A'*A).
%
% A must be square for p=metis(A) or metis(A,'sym')
%
