mario.calc_Z(z, X)

Calculate the Z intersectoral transaction flows matrix.

\[Z = z\,\operatorname{diag}(X)\]

Parameters:

• z (pandas.DataFrame) – z intersectoral transaction coefficients matrix.

• X (pandas.DataFrame) – X total production vector. Its index must match the columns of z.

Returns:

Z intersectoral transaction flows matrix. Each column of z is scaled by the corresponding production value in X.

Return type:

pandas.DataFrame
