Daniel@0: Purpose Daniel@0:

Daniel@0: Calculate function value along a line. Daniel@0: Daniel@0:

Daniel@0: Description Daniel@0:

Daniel@0: linef(lambda, fn, x, d) calculates the value of the function Daniel@0: fn at the point x+lambda*d. Here x is a row vector Daniel@0: and lambda is a scalar. Daniel@0: Daniel@0:

linef(lambda, fn, x, d, p1, p2, ...) allows additional Daniel@0: arguments to be passed to fn(). Daniel@0: This function is used for convenience in some of the optimisation routines. Daniel@0: Daniel@0:

Daniel@0: Examples Daniel@0:

Daniel@0: An example of Daniel@0: the use of this function can be found in the function linemin. Daniel@0: Daniel@0:
