Method new()

This method creates a valid 'TrapezoidalFuzzyNumber' object with all its attributes set.

Usage

TrapezoidalFuzzyNumber$new(inf0 = NA, inf1 = NA, sup1 = NA, sup0 = NA)

Arguments

inf0

is a real number that corresponds to the infimum of support of the trapezoidal fuzzy number.

inf1

is a real number that corresponds to the infimum of core of the trapezoidal fuzzy number

sup1

is a real number that corresponds to the supremum of core of the trapezoidal fuzzy numbers

sup0

is a real number that corresponds to the supremum of support of the trapezoidal fuzzy numbers

Details

See examples.

Returns

The TrapezoidalFuzzyNumber object created with all its attributes set if it is valid.

Examples

# Example 1:
TrapezoidalFuzzyNumber$new(1,2,3,4)

# Example 2: TrapezoidalFuzzyNumber$new(-8,-6,-4,-2)

# Example 3: TrapezoidalFuzzyNumber$new(-1,-1,2,3)

# Example 4: TrapezoidalFuzzyNumber$new(1,2,3,3)

Method is_positive()

This method gives information whether the 'TrapezoidalFuzzyNumber' is positive regarding its attributes.

Usage

TrapezoidalFuzzyNumber$is_positive()

Details

See examples.

Returns

TRUE whether the TrapezoidalFuzzyNumber object has all its attributes greater than -1, otherwise FALSE.

Examples

Arguments

color

is the color of the lines representing the number to be shown in the graph. The default value is grey, other colors can be specified, the option palette() too.

Details

See examples.

Returns

a graph with the values of the corresponding 'TrapezoidalFuzzyNumber'.

Examples

# Example 1:
TrapezoidalFuzzyNumber$new(1,2,3,4)$plot()

# Example 2: TrapezoidalFuzzyNumber$new(-8,-6,-4,-2)$plot("blue")

# Example 3: TrapezoidalFuzzyNumber$new(0,0,0.5,3)$plot(palette())
