Description: # Delaunay-ÄŒech filtrations
        
        This package provides functions for computing the smallest enclosing ball
        radius (miniball radius) of sets of three points in two and three dimensions and
        four points in three dimensions.
        
        These are used to produce Delaunay-ÄŒech filtrations, which can be used to
        compute ÄŒech persistence diagrams of points in two and three dimensions.
        
        ## Installation
        
        The `setuptools`, `numpy`, `scipy`, and `gudhi` Python packages are
        prerequisites for using this package.
        
        The last one can be installed with `conda` running
        
        ```
        >>> conda install -c conda-forge gudhi
        ```
        
        You'll also need `pybind11`, `cmake` and a `C++` compiler in order to install this
        package. It is recommended to install both `pybind11` and `cmake` via `conda`.
        
        ```
        >>> conda install -c anaconda cmake
        >>> conda install -c conda-forge pybind11
        ```
        
        Finally run the following command to build and install this Python package
        
        ```
        >>> pip install git+https://github.com/gbeltramo/delcechfiltr.git
        ```
        
        **Windows.** After installing `conda`, run the above commands within an
        `Anaconda prompt`. For the C++ compiler install
        <a href="https://visualstudio.microsoft.com/vs/">Visual Studio community</a>.
        
        ## Basic usage
        
        ```python
        import numpy as np
        import delcechfiltr.dgms
        
        n, d = 20, 3
        np.random.seed(0)
        pts = np.random.rand(n, d)
        
        dgm_H0_cech1, dgm_H1_cech1                        = delcechfiltr.dgms.cech(pts, persistence_dim_max=False)
        dgm_H0_cech2, dgm_H1_cech2, dgm_H2_cech2          = delcechfiltr.dgms.cech(pts, persistence_dim_max=True)
        dgm_H0_delcech1, dgm_H1_delcech1                  = delcechfiltr.dgms.delcech_3D(pts, persistence_dim_max=False)
        dgm_H0_delcech2, dgm_H1_delcech2, dgm_H2_delcech2 = delcechfiltr.dgms.delcech_3D(pts, persistence_dim_max=True)
        ```
