Hi MAZBAHUR KHAN,

To solve this issue, you can try out the following steps,

Increase input range values of the fuzzy inference system (FIS).
Limit input values to individual input range values before you feed it to the FIS.
Make sure the rules cover all the input space so that at least one rule is fired during the inference process. Look at the control surface of the FIS.
In evalfisOptions object, set diagnostic messages to "none".

If the issue is not solved please share your model to reproduce the issue,

Hope this helps!
