PETSc is a sophisticated package; and fully
understanding its usage requires time. However, application programmers can easily begin
to use PETSc from a high level, and then gradually learn more details according to
their needs. Users should read the users manual before attempting to do any serious coding
with PETSc!
The manual pages are split into four categories; we recommend that you begin with basic
functionality and then gradually explore more sophisticated library features.
Beginner - Basic usage
Intermediate - Setting options for algorithms and data structures
Advanced - Setting more advanced options and customization
Developer - Interfaces intended primarily for library developers, not for typical
applications programmers
