% @deftypefn {Function File} {@var{yi} =} interp1q (@var{x}, @var{y}, @var{xi})
% One-dimensional linear interpolation without error checking.
% Interpolates @var{y}, defined at the points @var{x}, at the points
% @var{xi}. The sample points @var{x} must be a strictly monotonically
% increasing column vector. If @var{y} is an array, treat the columns
% of @var{y} separately. If @var{y} is a vector, it must be a column
% vector of the same length as @var{x}.
%
% Values of @var{xi} beyond the endpoints of the interpolation result
% in NA being returned.
%
% Note that the error checking is only a significant portion of the
% execution time of this @code{interp1} if the size of the input arguments
% is relatively small. Therefore, the benefit of using @code{interp1q}
% is relatively small.
