Hi, the probem you are describing seems to be a typical application for the GSL library. You should use the numerical integration routines to perform the integral:
http://www.gnu.org/software/gsl/manual/html_node/Numerical-Integration.html <http://www.gnu.org/software/gsl/manual/html_node/Numerical-Integration.html>and then use the one-dimension root finding routines to solve the equation: http://www.gnu.org/software/gsl/manual/html_node/One-dimensional-Root_002dFinding.html I hope that's helpful. <http://www.gnu.org/software/gsl/manual/html_node/One-dimensional-Root_002dFinding.html>Best regards, Francesco 2010/8/6 Victor Bezerra <[email protected]> > Hi GSL team, > > I would like to ask if using GSL package, is possible solve a system of > equation, which in these equation some numerical integration is needed?
