sort_rows_infnorm()

template<typename Scalar >

void syten::sort_rows_infnorm	(	DenseTensor< 2, Scalar > &	a,
		DenseTensor< 2, Scalar > &	p
	)

Sorts the rows of a in-place such that the row with the largest absolute value comes first, then the row with the second-largest absolute value etc.

p is set to the permutation matrix required to construct the original a as prodD<1>(p, a, {-1, 1}, {1, -2}).
