|
//| Implementation of Fuzzy library in MetaQuotes Language 5 |
|
||
|
|
//| |
|
||
|
|
//| The features of the library include: |
|
||
|
|
//| - Create Mamdani fuzzy model |
|
||
|
|
//| - Create Sugeno fuzzy model |
|
||
|
|
//| - Normal membership function |
|
||
|
|
//| - Triangular membership function |
|
||
|
|
//| - Trapezoidal membership function |
|
||
|
|
//| - Constant membership function |
|
||
|
|
//| - Defuzzification method of center of gravity (COG) |
|
||
|
|
//| - Defuzzification method of bisector of area (BOA) |
|
||
|
|
//| - Defuzzification method of mean of maxima (MeOM) |
