% Prepend (append) the scalar value @var{c} to the vector @var{x}
% until it is of length @var{l}. If the third argument is not
% supplied, a value of 0 is used.
%
% If @code{length (@var{x}) > @var{l}}, elements from the beginning (end) of
% @var{x} are removed until a vector of length @var{l} is obtained.
%
% If @var{x} is a matrix, elements are prepended or removed from each row.
%
% If the optional @var{dim} argument is given, then operate along this
% dimension.
