# StackedFunction

class StackedFunction(memberFunctions: List<UnivariateFunction>, operation: (operands: List<Double>) -> Double, defaultValue: Double = Double.NaN) : UnivariateFunction

Stacks multiple functions and outputs the value according to the defined operation.

#### Parameters

memberFunctions

functions to be stacked together

operation

operation which combines the values of each member function

defaultValue

the default value, if one of the member functions is not defined at the requested parameter

fun slope(x: Double): Either<Exception, Double>

Evaluation of the slope = f'(x) with strict checking whether x is within the function's domain.

fun slopeInFuzzy(x: Double, tolerance: Double): Either<Exception, Double>

Evaluation of the slope = f(x) with fuzzy checking whether x is within the function's domain.
