Numerical operations on polytopes, ellipsoids, and subspaces

NumPES

NumPES is a controls-oriented Python package for performings numerical operations on polytopes, ellipsoids, and subspaces. Its classes are implemented as emulating numeric types, enabling a breadth of operations to be performed and evaluated. A modern scientific computing package implemented in Python, using C/C++ as a backend for efficient computation.

Installation

The easiest way to instal NumPES is by running

pip install numpes

in your terminal or dedicated virtual environment. Then, import NumPES using

import numpes as pes

at the top of your script to make its functionalities available.

Quick start

NumPES allows you to construct polytope, ellipsoid, and subspace objects and manipulate these. For example, start by initializing a polytope represented by its half-space representation (H-representation).

import numpy as np
import numpes as pes

A = np.array([[ 0,  1],
              [-2,  0],
              [ 1,  1],
              [ 0, -1]])
b = np.array([1, 1, 1, 0])

poly = pes.poly(A, b)  # Defines a polytope A x <= b

poly.plot(show=True)
