@deftypefnx {Loadable Function} {[@var{x}, @var{rcond}] =} inverse (@var{a})\n\
Compute the inverse of the square matrix @var{a}. Return an estimate\n\
of the reciprocal condition number if requested, otherwise warn of an\n\
ill-conditioned matrix if the reciprocal condition number is small.\n\
\n\
If called with a sparse matrix, then in general @var{x} will be a full\n\
matrix, and so if possible forming the inverse of a sparse matrix should\n\
be avoided. It is significantly more accurate and faster to do\n\
@code{@var{y} = @var{a} \\ @var{b}}, rather than\n\
@code{@var{y} = inv (@var{a}) * @var{b}}.\n\
