UPDATE (April 19, 2016): The impulse() function for FOTF objects has been fixed and the toolbox has been updated to version 1.21b. Download the new version now.

We would like to announce the update of FOMCON toolbox for MATLAB to version 1.2b. Please note that this is a beta release which is intended mostly for evaluation of new features. Previously available features should work as before.

New features
• Initial support for working with fractional-order state-space models including a Simulink block through the use of FOSS objects. Therefore, fractional-order MIMO systems can now be studied using FOMCON. Because the feature set is preliminary, the release is in “beta” status and previous documentation will not be updated at this time.
Various improvements
• Started to rewrite some of the basic FOTF support functions (step, impulse, etc.) to make them more compatible with Control System toolbox.
• Added the possibility to set computation accuracy for internal operations with FOTF objects. It can be set in the FOMCON options structure.
Bug fixes
• Evaluation of FOTF objects with small coefficients should now work. See the description of the above mentioned improvement. See the associated bug report.

Please note that the toolbox has been updated to version 1.21b. This small update is meant to fix the issues with the impulse() function that is used for impulse response computation for FOTF objects.
