libgslcblas0 - 2.6+dfsg-2 main

The GNU Scientific Library (GSL) is a collection of routines for
numerical analysis. The routines are written from scratch by the GSL
team in C, and present a modern API for C programmers, while allowing
wrappers to be written for very high level languages.
.
GSL includes data types and routines for complex numbers, vectors,
matrices, basic linear algebra subroutines (BLAS), eigensystems,
simulated annealing, minimization, root finding, pseudo-random
numbers, least-squares fitting, fast Fourier transforms (FFT),
differential equations, quadrature, Monte Carlo integration, special
functions, physical constants, and much more.
.
This package provides the shared blas library required to run programs
compiled with GNU GSL. To compile your own programs you also need to
install libgsl-dev.
