Dumps SOS filter coefficients to file in C language format in forward order. Creates two files "filename.h" which defines the size of the array and declares the array as extern, and "filename.c" which contains the instance of the array variable. Only 5 terms are written per section, a0 is ignored. The output array order is {b0, b1, b2, -a1, -a2}.

he basic idea of the method of bisection is to start with an initial interval, [a0,b0], that is chosen so that f(a0)f(b0) < 0. (This guarantees that there is at least one root of the function f(x) within the initial interval.) We then iteratively bisect the interval, generating a sequence of intervals [ak,bk] that is guaranteed to converge to a solution to f(x) = 0.
