-## outputs:
-##   u: orthogonal basis of block krylov subspace
-##   h: Hessenberg matrix; if v is a vector then a u = u h
-##      otherwise h is meaningless
-##  nu: dimension of span of krylov subspace (based on eps1)
-## if b is a vector and k > m-1, krylov returns h = the Hessenberg
-## decompostion of a.
+## If @var{v} is a vector, then @var{h} contains the Hessenberg matrix
+## such that @code{a*u == u*h}.  Otherwise, @var{h} is meaningless.
+##
+## The value of @var{nu} is the dimension of the span of the krylov
+## subspace (based on @var{eps1}).
+##
+## If @var{b} is a vector and @var{k} is greater than @var{m-1}, then
+## @var{h} contains the Hessenberg decompostion of @var{a}.
+##
+## The optional parameter @var{eps1} is the threshold for zero.  The
+## default value is 1e-12.
+##
+## If the optional parameter @var{pflg} is nonzero, row pivoting is used
+## to improve numerical behavior.  The default value is 0.
