Methods| Name | Description | |
|---|---|---|
| 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) |
| 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) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
Remarks
The QAG algorithm is a simple adaptive integration procedure. The integration region is
divided into subintervals, and on each iteration the subinterval with the largest estimated
error is bisected. This reduces the overall error rapidly, as the subintervals become concentrated
around local difficulties in the integrand. These subintervals are managed by a
gsl_integration_workspace struct, which handles the memory for the subinterval ranges,
results and error estimates.
