##Fuzzy logic implements

Implementation of fuzzy logic in Intel Galileo® platform by @kalmik.

###Features

• FuzzyThread, running the fuzzy routine
• ServerThread, serving the fuzzy output on socket TCP

###Testing

####Time Analysis

fuzzy system with 7 membership functions ( MFS ) and 49 production rules and websockets server.

####Graphical comparison

With MATLAB® toolbox. With C routine

###How to use

####Code Example

• ADD MFS

  float pGN[4] = {-1,-1,-0.75,-0.5};
  float pMN[3] = {-0.75,-0.5,-0.25};
  float pPN[3] = {-0.5,-0.25,0};
  float pZZ[3] = {-0.25,0,0.25};
  float pPP[3] = {0,0.25,0.5};
  float pMP[3] = {0.25,0.5,0.75};
  float pGP[4] = {0.5,0.75,1,1};
  
  pertinence GN = {&pGN,4};
  pertinence MN = {&pMN,3};
  pertinence PN = {&pPN,3};
  pertinence ZZ = {&pZZ,3};
  pertinence PP = {&pPP,3};
  pertinence MP = {&pMP,3};
  pertinence GP = {&pGP,4};

• ADD Rule

   rule rules[49] = {
   {andOp(fuzzify(e,GN),fuzzify(ed,GN)), &GN},
   {andOp(fuzzify(e,GN),fuzzify(ed,MN)), &GN},
