par_for()

void Qrack::ParallelFor::par_for	(	const bitCapIntOcl	begin,
		const bitCapIntOcl	end,
		ParallelFunc	fn
	)

Call fn once for every numerical value between begin and end.

par_for_inc()

void Qrack::ParallelFor::par_for_inc	(	const bitCapIntOcl	begin,
		const bitCapIntOcl	itemCount,
		IncrementFunc	inc,
		ParallelFunc	fn
	)

Iterate through the permutations a maximum of end-begin times, allowing the caller to control the incrementation offset through 'inc'.

par_for_mask()

void Qrack::ParallelFor::par_for_mask	(	const bitCapIntOcl	begin,
		const bitCapIntOcl	end,
		const std::vector< bitCapIntOcl > &	maskArray,
		ParallelFunc	fn
	)

Skip over the bits listed in maskArray in the same fashion as par_for_skip.

par_for_qbdt()

void Qrack::ParallelFor::par_for_qbdt	(	const bitCapInt	begin,
		const bitCapInt	end,
		BdtFunc	fn
	)

Iterate over a QBDT tree.

par_for_set() [1/2]

void Qrack::ParallelFor::par_for_set	(	const std::set< bitCapIntOcl > &	sparseSet,
		ParallelFunc	fn
	)

Iterate over a sparse state vector.

par_for_set() [2/2]

void Qrack::ParallelFor::par_for_set	(	const std::vector< bitCapIntOcl > &	sparseSet,
		ParallelFunc	fn
	)

Iterate over a sparse state vector.

par_for_skip()

void Qrack::ParallelFor::par_for_skip	(	const bitCapIntOcl	begin,
		const bitCapIntOcl	end,
		const bitCapIntOcl	skipPower,
		const bitLenInt	skipBitCount,
		ParallelFunc	fn
	)

Skip over the skipPower bits.

For example, if skipPower is 2, it will count: 0000, 0001, 0100, 0101, 1000, 1001, 1100, 1101. ^ ^ ^ ^ ^ ^ ^ ^ - The second bit is untouched.

par_for_sparse_compose()

void Qrack::ParallelFor::par_for_sparse_compose	(	const std::vector< bitCapIntOcl > &	lowSet,
		const std::vector< bitCapIntOcl > &	highSet,
		const bitLenInt &	highStart,
		ParallelFunc	fn
	)

Iterate over the power set of 2 sparse state vectors.

par_norm()

real1_f Qrack::ParallelFor::par_norm	(	const bitCapIntOcl	maxQPower,
		const StateVectorPtr	stateArray,
		real1_f	norm_thresh = ZERO_R1_F
	)

Calculate the normal for the array, (with flooring).

par_norm_exact()

real1_f Qrack::ParallelFor::par_norm_exact	(	const bitCapIntOcl	maxQPower,
		const StateVectorPtr	stateArray
	)

Calculate the normal for the array, (without flooring.)
