sph2car

<p>3-element or n-by-3 matrix representing the spherical components (r,theta,phi) of n three-dimensional vectors. Here, theta=0...pi is the polar angle measured from the north pole and phi=0...2*pi is the azimuth measured positively from the x-axis (ISO 80000-2:2019 physics convention).</p>

<p>Convert 3D spherical to Cartesian coordinates</p>

Collection of auxiliary routines for efficient scientific computations in physics and astrophysics. These routines can be used for random number generation (e.g. from spherical and custom distributions), information and entropy analysis (e.g. used in Obreschkow et al. (2020) <doi:10.1093/mnras/staa445>), spatial statistics, such as special DFTs and Landy-Szalay estimators (Landy & Szalay (1993) <doi:10.1086/172900>), binning/gridding of point sets and 2D interpolation, Monte Carlo integration, vector arithmetics, coordinate transformations, unit conversions and cosmological distance calculations. Also includes a list of important physical constants, particularly useful in astrophysics.
