unitvector

<p>m-element vector or n-by-m matrix <code>x[1:n,1:m]</code> representing n m-element vectors</p>

<p>Compute the unit vectors for for a matrix of non-normalised vectors</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.
