Trouble with function genfis1

I am having trouble with the function genfis1. It keeps telling me there is an error in the code of genfis1 itself. I do have the fuzzy toolbox installed...

The error that is given:

Undefined function or variable 'in_n'.

Error in genfis1 (line62)

numMFs=numMFs*ones(1, in_n);

Can somebody tell me why this is happening?

Which MATLAB release are you using?

If you

dbtype genfis1

then what shows up on line 58?

[Jeroen Schoonderbeek]

Matlab 2017b

In line 58 this shows up:

ein_n = size(data, 2) - 1;

Answer 1

[Walter Roberson]

You appear to have accidentally edited your genfis1 file. In R2017b line 58 has

in_n = size(data, 2) - 1;

and you appear to have inserted an 'e' before that.

Thank you so much! I would never have found this myself...
