isParallel_highPrec()

template<typename Scalar >

std::pair< ParallelKind, Scalar > syten::isParallel_highPrec ( DenseTensor< 1, Scalar > const &  a, DenseTensor< 1, Scalar > const &  b  )

inline

Checks if two vectors are parallel with very high sensitivity and requiring the factor to be of magnitude between 1e-3 and 1e3.

See test/highprec_parallel.cpp for test cases.

Parameters

a	first vector
b	second vector

Returns

a pair {ParallelKind, c}.

The second tensor multiplied by \( c \) will give the first tensor if the two tensors are parallel.
