Importing from differintP: How Namespaces Work

Overview

The differintP package is designed to provide both a clean top-level API and full access to specialized functionality and helper modules. This page explains what you get when you import differintP, and how to access additional functionality that isn’t exposed at the top level.

Top-Level Imports

When you do:

import differintP

or

from differintP import *

You have access to the following main functions and classes (as listed in __all__):

  • GLcoeffs
  • GL
  • GLpoint
  • GL_gpu
  • GLI
  • CRONE
  • RLmatrix
  • RLcoeffs
  • RLpoint
  • RL
  • CaputoL1point
  • CaputoL2point
  • CaputoL2Cpoint
  • CaputoFromRLpoint
  • Weyl
  • Riesz
  • functions (as a submodule)

You can use them directly:

from differintP import GL, RL, GLpoint
result = GL(0.5, lambda x: x**2, 0, 1, 100)

Accessing the functions Submodule

functions.py provides several advanced or special functions (like poch, Beta, MittagLeffler). You can access them as:

from differintP import functions

val = functions.poch(3.5, 2)

Or import directly:

from differintP.functions import MittagLeffler

Modules Not Imported by Default

Some modules are not automatically imported into the top-level namespace to keep the API clean. These include:

  • special.py (e.g., GLpoint_via_GL, GLpoint_direct)
  • solvers.py (e.g., PCcoeffs, PCsolver)
  • utils.py (e.g., isInteger, isPositiveInteger, checkValues, functionCheck)

If you want to use functions from these files, import them directly:

from differintP.special import GLpoint_via_GL
from differintP.solvers import PCsolver
from differintP.utils import isInteger

Summary Table

Import Statement Result
from differintP import GL Imports the main GL function
import differintP.functions Imports all functions in functions.py as differintP.functions
from differintP.special import GLpoint_direct Accesses functions not at top-level
from differintP import * Imports all top-level API, including functions as a submodule

Recommendations

  • For general use: Stick to the main top-level API.
  • For advanced users: Import directly from submodules as needed.
  • If you are contributing or extending, check the full set of submodules for additional utilities.

If you have questions about importing or want something added to the top-level API, open an issue or pull request!
