Parameters:

• a (array_like) – NRTL aij parameters matrix

• b (array_like) – NRTL bij parameters matrix

• c (array_like) – NRTL cij parameters matrix

a

Example

import numpy as np

from yaeos import NRTL

a = np.array([[0, 0.3], [0.3, 0]])
b = np.array([[0, 0.4], [0.4, 0]])
c = np.array([[0, 0.5], [0.5, 0]])

nrtl = NRTL(a, b, c)
