WebJun 13, 2012 · 1 Answer Sorted by: 2 It's not that hard. Simply the function which will be calculated has a form F (x)=g (x)*w (x), where g (x) is a function which user has to define. w (x) is made using c parameter and has form: w (x)=1/ (x-c). So if we want to compute principal value for function f (x)=1/ (x-1) func1 should be: WebFeb 20, 2024 · Generally, you need to do more than download packages like gsl and put them into a local directory - they need to be built and installed, into a system-wide location such as /usr/local if you have sufficient privileges otherwise into your home directory.

WebDec 3, 2024 · The GSL routines define their integrand as a gsl_function, which expects a double argument and returns a double value. They are not therefore designed to deal with complex intermediate results, even if the final result is real. Mathematica is designed to deal with complex values. Dec 3, 2024 #8 CAF123 Gold Member 2,950 88 OK I see, thanks. WebThe following program will integrate your integral with GSL. I was unable to reproduce the result you quoted with Mathematica. Note that when c = e = 0, the Laguerre polynomials are always 1 for any value of x. The code below does a slightly more interesting case of c = 2, e = 3. The output is: result = 1.539250228072e+00 chevy hhr fuse box location
