How to see the firing strength using command line of a fuzzy System?

Hi, I have built a fuzzy system from scratch using the fuzzy logic toolbox. My FIS has a huge number of rules and I would like to see, after using the comand evalfis for a concrete example, which is the firing strength of each rule. The problems is that I can not figure out how to access to this information using command line.

Thak you for your help
