GNU Scientific Library

The GNU Scientific Library (GSL) is an open-source collection of mathematical tools designed for programmers. It provides functions for complex calculations like statistics, algebra, calculus, and differential equations, making it easier to develop accurate scientific and engineering software. Think of it as a digital toolkit that helps process data, run simulations, and solve mathematical problems efficiently without starting from scratch. GSL is widely used because it’s reliable, well-tested, and freely available, supporting various programming languages primarily in C.
