Reads off coefficients of a power series.
power.coef.one(power.series, n = 1000, k, ...)
power.coef.many(power.series, n = 1024, ...)A function from C to C. Note that its single argument must be named "s". Should be a power series.
Parameter for numerical riemann integration or for FFT.
The coefficient to get.
A Real number, the kth coefficient, for .one, or a vector of coefficients for .many.
