| Description |
Mu-Tools based Multivariable System Identification
The Musysid folder contains some useful tools for :
- black box MIMO system identification
- state space system fitting from a given frequency response
- converting frequency response data between the MU-TOOLS Toolbox and the SYSTEM IDENTIFICATION Toolbox formats.
There are 8 files:
- contents : describes the files in the musysid folder
- arx3 : arx MIMO system identification
- rarx3 : recursive arx MIMO system identification
- fre2sys : sys fitting from MIMO frequency response
- ffte : rough fft based MIMO transfer function estimate
- ff2vm : frequency format to varying matrices
- vm2ff : varying matrices to frequency format
- phasefix : move phase angles in the interval [-pi, pi] |

Improved Compatibility with Matlab 6.0 (only frequency function format translators needs the sys. ident. toolbox shipped with 5.3.1) |
| 02 Jun 2003 |
Signature updated in Contents.m |
| 12 May 2005 |
Renamed everything lowercase |
| 20 Feb 2007 |
Corrected a bug that prevented rarx3 to work on multiple output systems. |
