Octave Fuzzy Logic Toolkit Reviews

i am using ubuntu 18.04, and i can't even install it it says error >> pkg install -forge fuzzy-logic-toolkit warning: load_path: /home/rafeeq/octave/fuzzy-logic-toolkit-0.4.5: No such file or directory warning: load-path: update failed for '/home/rafeeq/octave/fuzzy-logic-toolkit-0.4.5', removing from path warning: load_path: /home/rafeeq/octave/fuzzy-logic-toolkit-0.4.5: No such file or directory warning: load-path: update failed for '/home/rafeeq/octave/fuzzy-logic-toolkit-0.4.5', removing from path warning: load_path: /home/rafeeq/octave/fuzzy-logic-toolkit-0.4.5: No such file or directory warning: load-path: update failed for '/home/rafeeq/octave/fuzzy-logic-toolkit-0.4.5', removing from path parse error near line 165 of file /home/rafeeq/octave/fuzzy-logic-toolkit-0.4.5/defuzz.m anonymous function bodies must be single expressions >>> y_val = @(y_val) if (y_val == max_y) 1 else 0 endif; ^ error: called from doc_cache_create>create_cache at line 109 column 20 gen_doc_cache_in_dir>@<anonymous> at line 143 column 16 doc_cache_create>gen_doc_cache_in_dir at line 144 column 9 doc_cache_create at line 55 column 12 install>generate_lookfor_cache at line 794 column 5 install at line 223 column 7 pkg at line 441 column 9

I've used the Toolkit for some control projects and have reported on it in my blog: johnbakeree.blogspot.com/2015/01/octave-and-fuzzy-logic-for-paint-flow. I have used the Toolkit for only the Mamdani analysis and found it quite useful and easy to use, but quite slow on my ASUS notebook PC, probably because Octave is an interpreter language. However, I do find the Toolkit lacking in that it doesn't produce a LUT that I can use in my other programs such as LabWindows/CVI or C#. Back in January 2015 I was able to insert code into the gensurf function to get it to output the LUT in a file but subsequently I had trouble with my PC and I lost my code when I reinstalled Win7 and have not been able to regenerate it. :-( If LMarkowsky would provide the code for me, I would appreciate it very much. Anyhow, thanks LMarkowsky for providing such a useful toolkit. John
