SIGMA_NEG_ONLY property

int SIGMA_NEG_ONLY
read / write

Returns sigma of matrix by evaluating a 16x16 square at the top left of the spectrum (outside nmr diagonal) posneg is one of SIGMA_POS_ONLY, SIGMA_NEG_ONLY, SIGMA_POS_NEG. It defines whether only positive, negative or all numbers in the region should contribute to sigma.

Implementation

static int SIGMA_POS_ONLY = 0, SIGMA_NEG_ONLY = 1
