The attached Matlab file is an implementatation of the frequency domain subspace system identification algorithm described in “Subspace Based Multivariable System Identification from Frequency Response Data”, IEEE Transactions on Automatic Control, Vol. 41, No.7, July 1996. This tool allows SISO or MIMO models to be obtained from frequency response data. It is available free of charge.
