Triangular Fuzzy Numbers
- class pyfdm.TFN.tfn.TFN(a, b, c)[source]
Bases:
object- __add__(other) TFN[source]
Overloads the ‘+’ operator for addition of Triangular Fuzzy Numbers. Also handling an addition with number.
Returns a new Triangular Fuzzy Number representing the sum.
- __eq__(other: TFN) bool[source]
Checks if two Triangular Fuzzy Numbers are equal. Returns True if they are equal, False otherwise.
- __mul__(other) TFN[source]
Overloads the ‘*’ operator for multiplication of Triangular Fuzzy Numbers. Also handling a multiplication by number.
Returns a new triangular fuzzy number representing the product.
- __sub__(other) TFN[source]
Overloads the ‘-’ operator for subtraction of Triangular Fuzzy Numbers. Also handling a subtraction with number.
Returns a new Triangular Fuzzy Number representing the difference.
- __truediv__(other: TFN) TFN[source]
Overloads the ‘/’ operator for division of Triangular Fuzzy Numbers. Also handling a division by number.
Returns a new Triangular Fuzzy Number representing the quotient.
Raises a ValueError if the denominator contains zero.
- centroid() float[source]
Calculates the centroid of the Triangular Fuzzy Number.
Returns: - float: The centroid of the Triangular Fuzzy Number.
- core() list[source]
Calculates the core of the Triangular Fuzzy Number.
Returns: - list: A list containing the core values of the Triangular Fuzzy Number.
- is_included_in(other: TFN) bool[source]
Checks if the current Triangular Fuzzy Number is included in the other.
Returns: - bool: True if the current Triangular Fuzzy Number is included in the other, False otherwise.
- membership_function(x: float | ndarray) float | ndarray[source]
Calculates the membership function value at a given point x. Also handles calculation for an array of values.
Parameters: - x (float): The point at which to calculate the membership function.
Returns: - float: The membership function value at the given point x.
