Hi all,
A new "Matrix Fitting Toolbox" is available on
http://www.energy.sintef.no/produkt/VECTFIT/index.asp
(Click on "Downloads")
The toolbox extracts rational models for Y-parameter and S-parameter data cases.
- Routine VFdriver.m calculates a symmetrical and causal rational model with
stable poles using vector fitting.
- Routine RPdriver.m enforces passivity by perturbing eigenvalues of residue
matrices.
Compared to earlier versions found on this web site, the new code is faster and
more robust, and the passivity enforcement step is also applicable to
S-parameter cases.
The code is matlab source files and can bee freely used by anyone. Some
restrictions apply for commercial use.
Best regards,
Bjorn Gustavsen
