// Four main theta functions with various flavors of parameterization,
// floating-point policies, and bonus "minus 1" versions of functions 3 and 4
// designed to preserve accuracy for small q. Twenty-four C++ functions are
// provided in all.
//
// The functions take a real argument z and a parameter known as q, or its close
// relative tau.
//
// The mathematical functions are best understood in terms of their Fourier
// series. Using the q parameterization, and summing from n = 0 to ∞:
//
// θ₁(z,q) = 2 Σ (-1)ⁿ * q^(n+1/2)² * sin((2n+1)z)
// θ₂(z,q) = 2 Σ q^(n+1/2)² * cos((2n+1)z)
// θ₃(z,q) = 1 + 2 Σ q^n² * cos(2nz)
// θ₄(z,q) = 1 + 2 Σ (-1)ⁿ * q^n² * cos(2nz)
//
// Appropriately multiplied and divided, these four theta functions can be used
// to implement the famous Jacabi elliptic functions - but this is not really
// recommended, as the existing Boost implementations are likely faster and
// more accurate.  More saliently, setting z = 0 on the fourth theta function
// will produce the limiting CDF of the Kolmogorov-Smirnov distribution, which
// is this particular implementation’s raison d'être.
//
// Separate C++ functions are provided for q and for tau. The main q functions are:
//
// template <class T> inline T jacobi_theta1(T z, T q);
// template <class T> inline T jacobi_theta2(T z, T q);
// template <class T> inline T jacobi_theta3(T z, T q);
// template <class T> inline T jacobi_theta4(T z, T q);
//
// The parameter q, also known as the nome, is restricted to the domain (0, 1),
// and will throw a domain error otherwise.
//
// The equivalent functions that use tau instead of q are:
//
// template <class T> inline T jacobi_theta1tau(T z, T tau);
// template <class T> inline T jacobi_theta2tau(T z, T tau);
// template <class T> inline T jacobi_theta3tau(T z, T tau);
// template <class T> inline T jacobi_theta4tau(T z, T tau);
//
// Mathematically, q and τ are related by:
//
// q = exp(iπτ)
//
// However, the τ in the equation above is *not* identical to the tau in the function
// signature. Instead, `tau` is the imaginary component of τ. Mathematically, τ can
// be complex - but practically, most applications call for a purely imaginary τ.
// Rather than provide a full complex-number API, the author decided to treat the
// parameter `tau` as an imaginary number. So in computational terms, the
// relationship between `q` and `tau` is given by:
//
// q = exp(-constants::pi<T>() * tau)
//
// The tau versions are provided for the sake of accuracy, as well as conformance
// with common notation. If your q is an exponential, you are better off using
// the tau versions, e.g.
//
// jacobi_theta1(z, exp(-a)); // rather poor accuracy
// jacobi_theta1tau(z, a / constants::pi<T>()); // better accuracy
//
// Similarly, if you have a precise (small positive) value for the complement
// of q, you can obtain a more precise answer overall by passing the result of
// `log1p` to the tau parameter:
//
// jacobi_theta1(z, 1-q_complement); // precision lost in subtraction
// jacobi_theta1tau(z, -log1p(-q_complement) / constants::pi<T>()); // better!
//
// A third quartet of functions are provided for improving accuracy in cases
// where q is small, specifically |q| < exp(-π) ≅ 0.04 (or, equivalently, tau
// greater than unity). In this domain of q values, the third and fourth theta
// functions always return values close to 1. So the following "m1" functions
// are provided, similar in spirit to `expm1`, which return one less than their
// regular counterparts:
//
// template <class T> inline T jacobi_theta3m1(T z, T q);
// template <class T> inline T jacobi_theta4m1(T z, T q);
// template <class T> inline T jacobi_theta3m1tau(T z, T tau);
// template <class T> inline T jacobi_theta4m1tau(T z, T tau);
//
// Note that "m1" versions of the first and second theta would not be useful,
// as their ranges are not confined to a neighborhood around 1 (see the Fourier
// transform representations above).
//
// Finally, the twelve functions above are each available with a third Policy
// argument, which can be used to define a custom epsilon value. These Policy
// versions bring the total number of functions provided by jacobi_theta.hpp
// to twenty-four.
