Skew-Hermitian matrix

LIX is a readability measure indicating the difficulty of reading a text developed by Swedish scholar Carl-Hugo Björnsson. It is computed as follows:

$\text{LIX}=\frac{A}{B}+\frac{C\cdot 100}{A}$, where

$A$ is the number of words,

$B$ is the number of periods (defined by period, colon or capital first letter), and

$C$ is the number of long words (more than 6 letters).
