Abstract: The invention relates to a method of determining a transfer function (TRF) of a module (MDL). To improve accuracy of such methods the invention proposes the steps: a. measuring a first set-of-sensors-output (SOI) applied to said module (MDL) and measuring a second set-of-sensors-output (SO2); b. deducing a transfer function (TRF) of said module (MDL), wherein a transfer-function matrix (MTM) is a quadratic n-dimensional matrix for said n degrees of freedom (DOF); c. selecting a submatrix (SBM); d. determining for said selected submatrix (SBM) a corresponding rotational matrix (RTM) which improves the symmetry of the submatrix (SBM); e. generating a main rotational matrix (MRM) to transform said main transfer-function matrix (MTM); f. providing the transfer function (TRF) with said transformed transfer-function matrix (TTM).
