How to fix Undefined function or variable 'anfisOptions'.

Not able to run 'anfisOptions' function

Answer 1

[Star Strider]

The anfisOptions function was introduced in R2017a.

If you have the R2017a version of the Fuzzy Logic Toolbox, and you cannot access the function, first try running these lines from your Command Window or a script:

restoredefaultpath 
rehash toolboxcache

If that fails, Contact Support.

Thank you. I was using R2016b. I guess that was the problem.

[Star Strider]

My pleasure.

Sorry.

I tried this and now I cannot run any functions.

Hi,

fis = anfis(trainingdata,opt);

The opt was also introduced in R2017a? I try to replace the anfisOptions with opt.InitialFIS = 4; opt.EpochNumber = 30; but it doesnt work with

fis = anfis(trainingdata,opt);

Thanks, Kong
