|
| //| 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) |
