For a system of m phases and n samples (where n ? m), and sum of weight % of all phases is 100%, a set of equations is derived of the form:
100 = K1I11 + K2I12 + … + Km I1m
100 = K1I21 + K2I22 + … + Km I2m
100 = K1In1 + K2In2 + … + Km Inm
ie this is a matrix of the form L = IK
with L and K being column matrices with the elements 100 and the KJ ‘s respectively, and I a rectangular matrix containing the IiJ ‘s.
