Manolis - do you have the Fuzzy Logic Toolbox? In the command window, type
which genfis1
to see if MATLAB can find the function. If it can, then which version of MATLAB are you using?

Thank you both for the instant reply. I typed that but the following came out:
>> which genfis1 'genfis1' not found.
>> which genfis 'genfis' not found.
I am using the "MATLAB R2014a" version.

genfis1 was part of the Fuzzy Logic toolbox from some time before R2006a, so if you have the Fuzzy Logic Toolbox installed you should have the function. Perhaps you do not have that toolbox installed. Command
ver('fuzzy')
If you have the toolbox installed then it should list the toolbox.
