Is there a complex library for the Nerdkits? I'm doing some IIR filter stuff and I need complex math. I know I can make my own which I started, but someone else could probably do a better job.

here is my complex.h file so far

struct Comp
{
    double Re;
    double Im;
};

struct Comp AddComplex(struct Comp A, struct Comp B)
{
    struct Comp D;

    D.Re = A.Re + B.Re;
    D.Im = A.Im + B.Im;

    return D;
}

struct Comp MulComplex(struct Comp A, struct Comp B)
{
    struct Comp D;

    D.Re = A.Re*B.Re - A.Im*B.Im;
    D.Im = A.Re*B.Im + A.Im*B.Re;

    return D;
}

sorry for the double post I got an error the first time, so I re did it only to find out the first one worked. Nerdkits web site is little wacky. Any ways lets use this one thread

Scooter,

Probably more than you need, but complex number functions included here: science library
