[IoId("00000000-123b-451a-81b7-d4149b264b93")] public sealed class UnaryArithmeticFunction : FunctionF<Function>
Utility function for applying standard arithmetic to functions.

Constructors

UnaryArithmeticFunction

#
public UnaryArithmeticFunction(Function underlying, Unary unary)
Create a new unary modifier function.
underlying (Function)
unary (Arithmetic.Unary)

UnaryArithmeticFunction

public UnaryArithmeticFunction(IReader reader)
reader (IReader)

Properties

Derivative

public sealed override Function Derivative { get; }
Gets a function which is the derivative of this function. The returned function may be either analytic or approximate.
inherited fromFunctionWithCaching

F

public T1 F { get; }
First operand.
inherited fromFunctionF<T1>

Integral

public sealed override Function Integral { get; }
Gets a function which is the indefinite integral of this function. The returned function may be analytic or approximate. Note that numeric approximation of indefinite integrals is a slow and not particularly high quality process.
inherited fromFunctionWithCaching

Nomen

public sealed override Nomen Nomen { get; }
Gets a description of this function.
inherited fromFunctionWithCaching
Function.Nomen

Notation

#
public override string Notation { get; }

Ui

public virtual FunctionUi Ui { get; }
Gets a UI object for modifying this function. This property may return null, not all functions must be editable.
inherited fromFunction

Unary

#
public Arithmetic.Unary Unary { get; }
Gets the unary function which is applied.

Methods

Asymptotes

public virtual Line[] Asymptotes()
Returns an array of *all* the non-vertical asymptotes for this function. This property may return both null and empty arrays, implying no asymptotes. Due to the nature of non-vertical asymptotes, there can only be a finite amount of them.
inherited fromFunction

AutoCoDomain

protected void AutoCoDomain(double x0, double x1, out double y0, out double y1, int samples = 100)
Compute the automatic codomain for a given domain.
inherited fromFunction
x0 (double)Domain start.
x1 (double)Domain end.
y0 (out double)Lowest value in codomain.
y1 (out double)Highest value in codomain.
samples (int = 100)Samples.

DomainEstimate

public override void DomainEstimate(out double x0, out double x1, out double y0, out double y1)
inherited fromFunctionF<T1>
x0 (out double)
x1 (out double)
y0 (out double)
y1 (out double)

EmitDerivative

protected virtual Function EmitDerivative()
Override this method to provide an analytic derivative.
inherited fromFunctionWithCaching

EmitIntegral

protected virtual Function EmitIntegral()
Override this method to provide an analytic indefinite integral.
inherited fromFunctionWithCaching

Holes

public override Interval[] Holes(double x0, double x1)
inherited fromFunctionF<T1>
x0 (double)
x1 (double)
Function.Holes

Integrate

public virtual double Integrate(double x0, double x1)
Evaluate the definite integral between two parameters. Unless a function specifically implements an analytic integral, this value will be approximate. Note to implementer: if you provide an analytic integral via the Function.Integral property, that function will be used to compute an analytic result. There is typically no reason to override this method.
inherited fromFunction
x0 (double)Integral start.
x1 (double)Integral end.
Definite integral from x0 to x1.

Poles

public override Pole[] Poles(double x0, double x1)
inherited fromFunctionF<T1>
x0 (double)
x1 (double)
Function.Poles

Store

#
public override void Store(IWriter writer)
writer (IWriter)

Y

#
public override double Y(double x)
x (double)
Function.Y

YYYY

public double[] YYYY(double[] x)
Evaluate a large amount of values. Functions may choose to use multiple threads to perform this calculation. This method should not throw, instead every failed evaluation will be represented by a NaN value.
inherited fromFunction
x (double[])Value to evaluate.
Evaluation results. Array will contain double.NaN entries for failed evaluations.
