示例1: test_FFT_works
void Test::test_FFT_works() {
srand(time(0));
int n = 4;
Vector<Complex> P(n);
int randMin = -100, randMax = 100;
for(int i = 0; i < n; ++i) {
double real = rand()%(randMax-randMin)+randMin;
double imaginary = rand()%(randMax-randMin)+randMin;
P[i] = Complex(real, imaginary);
}
// P[0] = Complex(2,0);
// P[1] = Complex(2,0);
// P[2] = Complex(2,0);
// P[3] = Complex(2,0);
Vector<Complex> x = Vector<Complex> (n);
for(int i = 0; i < n; i++) {
x[i] = Complex(cos(2*PI/n * i), sin(2*PI/n * i));
}
