Detailed Description

Adds the ability to compute phi(alpha) at alpha of a given set of vectors.

Computes phi( x = sum( alpha^k * d[k], k = 0...p-1 ) ) where 1 <= p <= 2.

Constructor & Destructor Documentation

ConstrainedOptPack::MeritFuncCalc1DQuadratic::MeritFuncCalc1DQuadratic	(	const MeritFuncCalc &	phi,
		size_type	p,
		const_VectorWithOp_ptr	d[],
		VectorMutable *	x
	)

The only constructor.

Note that *x and *d gets updated as operator()(alpha) is called.

The client must ensure that the memory pointed to by the vectors in d must not be desturbed while this object is in use. To do so may have bad side effects.

Parameters

phi	[in] The merit function to use.
p	[in] The number of vectors in `d`[].
d	[in] Array (length `p`) of pointers to the rhs `d`[] vectors.
x	[out] The vector that gets updated.
