Setting Up GNU Scientific Library (GSL)
Introduction I have a few scientific computing projects that I would like to do which will require a good numerical methods library. I am going to try to use GSL. Getting the Library Getting the library install was easy enough, just needed to use apt-get sudo apt-get install libgsl-dev To check that the installation succeeded: ldconfig -p | grep gsl Which resulted in: First Example To test the library I grabbed a basic example from the documentation: #include <stdio.h> #include <gsl/gsl_sf_bessel.h> int main ( void ) { double x = 5.0 ; double y = gsl_sf_bessel_J0 (x); printf ( "J0(%g) = %.18e\n" , x, y); return 0 ; } and compiled it with the following: g++ main.cpp -lgsl -o test running the binary yields: which I guess is the value of the first Bessel Function at 5?
