## Region - RG

The RG package provides a way to define a region of the complex plane. This is used in various eigensolvers to specify where the wanted eigenvalues are located.

Beginner - Basic usage
| RG | RGIsTrivial | RGView
RGCreate | RGSetFromOptions |
RGDestroy | RGType |
Intermediate - Setting options for algorithms and data structures
| RGCheckInside | RGGetComplement | RGSetType
RGComputeBoundingBox | RGGetType | RGViewFromOptions
RGComputeContour | RGIsAxisymmetric |
RGComputeQuadrature | RGSetComplement |
Advanced - Setting more advanced options and customization
| RGAppendOptionsPrefix | RGIntervalSetEndpoints | RGRingGetParameters
RGEllipseGetParameters | RGPolygonGetVertices | RGRingSetParameters
RGEllipseSetParameters | RGPolygonSetVertices | RGSetOptionsPrefix
RGGetOptionsPrefix | RGQuadRule | RGSetScale
RGGetScale | RGRegister |
RGIntervalGetEndpoints | RGRegisterAll |
Developer - Interfaces intended primarily for library developers, not for typical applications programmers
| RGCanUseConjugates | RGInitializePackage | RGPushScale
RGFinalizePackage | RGPopScale |
