5.3 Complex arithmetic operators

Function: gsl_complex gsl_complex_add (gsl_complex a, gsl_complex b)
This function returns the sum of the complex numbers a and b, z=a+b.
Function: gsl_complex gsl_complex_sub (gsl_complex a, gsl_complex b)
This function returns the difference of the complex numbers a and b, z=a-b.
Function: gsl_complex gsl_complex_mul (gsl_complex a, gsl_complex b)
This function returns the product of the complex numbers a and b, z=ab.
Function: gsl_complex gsl_complex_div (gsl_complex a, gsl_complex b)
This function returns the quotient of the complex numbers a and b, z=a/b.
Function: gsl_complex gsl_complex_add_real (gsl_complex a, double x)
This function returns the sum of the complex number a and the real number x, z=a+x.
Function: gsl_complex gsl_complex_sub_real (gsl_complex a, double x)
This function returns the difference of the complex number a and the real number x, z=a-x.
