Hello,

I am learning fuzzy logic, and I want to implement a simple if statement. I dont want to use the toolbox because later i want to add the fuzzy logic to my matlab code in working on.

I checked the matlab help, but it explains how to use the toolbox.

If anyone can explain to me how to code:

if food is delicious, then tip is good.

This should be sufficient for me to progress from there.

Thanks.
