pymrio.calc_M_down

pymrio.calc_M_down(S, G)

Calculate downstream multipliers of the extensions.

M_down = S * ( G^T - I )

Where I is an identity matrix of same shape as G

Parameters

• G (pandas.DataFrame or numpy.array) – Ghosh input output table G

• S (pandas.DataFrame or numpy.array) – Direct impact coefficients

Returns

Downstream multipliers M The type is determined by the type of S. If DataFrame index/columns as S

Return type

pandas.DataFrame or numpy.array
