public class NLFit
The NLFit type exposes the following members.
ConstructorsMethods| Name | Description | |
|---|---|---|
  | ComputeCovariances | This will compute the covariances at a given parameter set xvec. |
| enorm(Int32, Double) | given an n-vector x, this function calculates the euclidean norm of x. |
| enorm(Int32, Double, Int32) | Given an n-vector x, this function calculates the euclidean norm of x. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| fdjac2 | This subroutine computes a forward-difference approximation to the m by n Jacobian matrix associated with a specified problem of m functions in n variables. |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| LevenbergMarquardtFit(NLFitLMFunction, Double, Double, Double, CancellationToken, Int32) | The purpose of LevenbergMarquardtFit is to minimize the sum of the squares of m nonlinear functions in n variables by a modification of the Levenberg-Marquardt algorithm. This is done by using the more general least-squares solver below. The user must provide a subroutine which calculates the functions. The Jacobian is then calculated by a forward-difference approximation. |

| lmpar | |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |

| sqr | |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
