C complex number usage

[Bruce Labitt]

I did find a solution.  Not online though...  From brute force try 
anything...
This snippet does work.  However, as noted in the code, even though the 
standard says it will work - it didn't...

#include <cstdlib>
#include <iostream>
#include <complex>
using namespace std;
using std::complex;

int main(int argc, char *argv[])
{
    int ii,N;
    N=1;
    double a, b;
    complex <double> c(10.8, 2.5);
    //double realpart,imagpart;
   
    a = 1.0;    // a is the real part
    b = 2.1;    // b is the imaginary part
    // c = a,b;  // This does not form the complex number!!!
                 // although the documentation says otherwise!
                // this prints out (1.0,0) not (1.0,2.1)
    cout << c << endl;
    c = complex<double>(a,b); 
    cout << c << endl;
     
    system("PAUSE");
    return EXIT_SUCCESS;
}

Back to my original problem... Massively long FFTs on complex data.
