sciFLT have the following properties:
=================================
    Types of Fuzzy Logic systems:  At this stage, sciFLT can deal with
Takagi-Sugeno Fuzzy and Mamdani fuzzy systems usage.

    XCOS support: Member functions, S-Norm, T-Norm, Complement and Fuzzy Logic
System (fls) are supported. Also include a palette.

    S-Norm Class supported: Dubois-Prade, Yager, Drastic sum, Einstein,  sum,
Algebraic sum, Maximum.

    T-Norm Class supported: Dubois-Prade, Yager, Drastic product, Einstein
product,  Algebraic product,  Minimum

    Complement Class supported:  One (classic), Yager, Dubois.

    Implication method supported: Product, Minimum

    Aggregation method supported: Algebraic Sum, Maximum

    Defuzzification method supported: Centroide, Bisector, Mean of Maximum,
Largest of Maximum, Smallest of Maximu, Weighted Average, Center Average.

    Member functions supported:  Triangular, Trapezoidal, Gaussian, Extended
Gaussian,  Sigmoidal,  Product of two Sigmoidal,  Difference of two sigmoidal,
S-Shaped, Z-Shaped, Pi-Shaped. Linear and Const as output for Takagi-Sugeno
type.

    GUI editor: Built in editor to change properties, inputs/outputs variables,
member functions, rules.

Hi again, 

Thanks for the update on the bug, 2 more bugs I've discovered:

1. gbellmf in the fotran source code:

c COMPUTE MEMBER FUNCTION
       do 20, j=1, n
        do 10, i=1, m
c         if (par(3).eq.0.D0) then
c          y(i,j)=0.5D0
c         elseif (par(3).lt.0.0D0) then
c	     y(i,j)=0.0D0
c         else
          tmp1=(x(i,j)-c)/a
          if (tmp1.lt.0.0D0) then
           tmp1=-tmp1
          endif
          tmp1=tmp1**(2.0D0*b)
          y(i,j)=1.0D0/(1.0D0+tmp1)
c         end if
10      continue
20     continue
       ierr=0
    
9999   return
       end

I believe the some lines should be taken out to allow the c = negative. 

2. Saving the fls file. 
- If one do not specify the file extension, it would be save without .fls. Some checking 
routine should have added to add the .fls automatically.

thanks again.

rgds,
CL

Dear Scilabs friends, good morning.  
  
I'm a Brazilian Scilab's user, OK!  
  
I am in trouble with some application of Scilab version 5.5.0.  
  
Describing my trouble:  
  
When I was working with Scilab module called Modeling and Control Tools, I needed  the
Fuzzy Logic Toolbox . At that time, I had to load the proper ATOMS for it from the Scilab
ATOMS site through the Internet  and so I obtained the SCIFLT is a Fuzzy Logic Toolbox
for  Scilab 0.4.5-1, the most recent version available, OK!  
  
But, in a contrary way of my desire, this operation introduced an error in my computer
system and I didnt deal well with this situation.  
  
Pay attention to this: my notebook working with WINDOWS 8 and my Scilab is the Scilab
5.5.0 and the Fuzzy Logic Toolbox version 0.4.4 worked very well, but the version  Scilab
0.4.5-1 is not working very well as I hope, OK.  
  
Please, can you help me?   
  
I hope so, and I will wait for an answer with attention.  
  
Thanks so much!!!

Hi all!

I report this litlle bug, i have a Manjaro x64 box, with scilab 5.4.1 but, when i used
xcos tool for fuzzy logic system, i can't load a fls file, 

I have another little examples, and they have loaded a fls file, but i can't chance the
file with fls file.

thank's in advance & i apologize for my bad english. sorry

Hi Luiz,

Are you using the atomsInstall or compile from source? I found out that this version 
having some minor issues on the binary version but it works fine if you compile from 
source.

thanks

Thanks for attention!!!

Asking your question: I'm using the ATOMSINSTALL, OK!!!

Thanks!

In addition to my question, I am attaching the message when I restarted the Scilab 5.5.0
after loadding Fuzzy archives from AtomsInstall: [Unfortunately the message text from
Scilab is in Portuguse].

Execuo de iniciao:

Start Fuzzy Toolbox 0.4.6
	Load macros
	Load shared library
atomsLoad: Ocorreu um erro durante o carregando de 'sciFLT-0.4.6-1':

Thanks...

Translation from Portuguese to English of the error message above:

Initial execution:
   loadding the initial environment

Start Fuzzy Toolbox 0.4.6
        Load macros
        Load shared library

atomsLoad: an error happened during the charging process of 'sciFLT-0.4.6-1':
        link: the sharing file was not charging: The name syntax of the file, nor the
directoty name, nor the volume label is not correct.



Thanks...
