// Compute the value of the gamma function at x = 2.5 result := gslsf.Gamma(2.5) if result.Err != nil { log.Fatalf("gamma(2.5) error: %v", result.Err) } fmt.Printf("gamma(2.5) = %v\n", result.Value) // Compute the Bessel function J_0(x) at x = 1.0 result = gslsf.BesselJ0(1.0) if result.Err != nil { log.Fatalf("J_0(1.0) error: %v", result.Err) } fmt.Printf("J_0(1.0) = %v\n", result.Value)The first example computes the value of the gamma function using the `Gamma` function provided by this package. If an error occurs during the computation, it prints a log message and exits with an error. Otherwise, it prints the computed value of the function. The second example computes the Bessel function `J_0(x)` using the `BesselJ0` function provided by this package. It does the same error checking and printing of the computed value as the first example. In summary, the go package library github.com.dtromb.gogsl.sf provides a collection of special functions implemented using the GNU Scientific Library. The `GslSfResult` type provided by this package represents the result of a call to one of these special functions, and the package provides a set of functions for computing various special functions.
