Hi,
I have been using your Toolbox lately, which I found to be very nice to work with. However I encountered something that didn't work out for me too well. For some Values the inverse function throws an assertion error.
I localized it in the file "power.m" and it happened for me for the case "3". It seemed that the assertion check failed if the scalar value in P is very big. Therefore I put the "normalization" step: P./component(A,1) before the assertion check, which solved the problem.
See whether you want to consider this in you new version or not.
Best regards,
André Behrends
