SyntaxThe BrentFindExtremum type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | BrentFindExtremum |
Initializes the extremum finding algorithm.
|
Properties| Name | Description | |
|---|---|---|
 | ConvergenceCriteria |
Gets the criteria used in determining convergence.
|
| Error |
Gets the error at this estimate in the quadratic approximation relative to the real function. This is the value
checked against the FunctionTolerance to determine convergence.
|
| Extremum |
Gets the current estimate of the extremum.
|
| ExtremumKind |
Gets whether this extremum is a minimum or maximum.
|
| Function |
Gets the evaluation function.
|
| FunctionTolerance |
Gets the convergence tolerance on the value of the function.
|
| HasConverged |
Gets a value indicating whether the algorithm is in the converged state.
|
| Iterations |
Gets the number of iterations taken.
|
| Value |
Gets the function value at the current estimate of the extremum.
|
| VariableTolerance |
Gets the convergence tolerance on the value of the variable.
|
Methods| Name | Description | |
|---|---|---|
| CheckInitialBracketingPoints(Double, Double, Double) |
Checks whether the given values will produce a valid initial bracketing interval.
|
 | CheckInitialBracketingPoints(Double, Double, Double, Double, Double, Double, Double) |
Checks whether the given values and function values will produce a valid initial bracketing interval.
|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| FindExtremum |
Attempts to locate a local extremum in the provided number of iterations.
|
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| SetInitialBracketingPoints(Double, Double, Double) |
Defines the initial bracketing interval using the provided variable values.
|
| SetInitialBracketingPoints(Double, Double, Double, Double, Double, Double) |
Defines the initial bracketing interval using the provided variable values and corresponding function values.
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
