% @deftypefn {Function File} {} cond (@var{a},@var{p})
% Compute the @var{p}-norm condition number of a matrix. @code{cond (@var{a})} is
% defined as @code{norm (@var{a}, @var{p}) * norm (inv (@var{a}), @var{p})}.
% By default @code{@var{p}=2} is used which implies a (relatively slow)
% singular value decomposition. Other possible selections are
% @code{@var{p}= 1, Inf, inf, 'Inf', 'fro'} which are generally faster.
