+%LINEF	Calculate function value along a line.

+%	Description
+%	LINEF(LAMBDA, FN, X, D) calculates the value of the function FN at
+%	the point X+LAMBDA*D.  Here X is a row vector and LAMBDA is a scalar.
+%
+%	LINEF(LAMBDA, FN, X, D, P1, P2, ...) allows additional arguments to
+%	be passed to FN().   This function is used for convenience in some of
+%	the optimisation routines.
