Called with two arguments, ``qp(a,q)`` computes `(a;q)_{\infty}`; with a single argument, ``qp(q)`` computes `(q;q)_{\infty}`. The special case .. math :: \phi(q) = (q; q)_{\infty} = \prod_{k=1}^{\infty} (1-q^k) = \sum_{k=-\infty}^{\infty} (-1)^k q^{(3k^2-k)/2} is also known as the Euler function, or (up to a factor `q^{-1/24}`) the Dedekind eta function. **Examples** If `n` is a positive integer, the function amounts to a finite product:: >>> from mpmath import * >>> mp.dps = 25; mp.pretty = True >>> qp(2,3,5) -725305.0 >>> fprod(1-2*3**k for k in range(5)) -725305.0 >>> qp(2,3,0) 1.0 Complex arguments are allowed:: >>> qp(2-1j, 0.75j) (0.4628842231660149089976379 + 4.481821753552703090628793j) The regular Pochhammer symbol `(a)_n` is obtained in the following limit as `q \to 1`:: >>> a, n = 4, 7 >>> limit(lambda q: qp(q**a,q,n) / (1-q)**n, 1) 604800.0 >>> rf(a,n) 604800.0 The Taylor series of the reciprocal Euler function gives the partition function `P(n)`, i.e. the number of ways of writing `n` as a sum of positive integers:: >>> taylor(lambda q: 1/qp(q), 0, 10) [1.0, 1.0, 2.0, 3.0, 5.0, 7.0, 11.0, 15.0, 22.0, 30.0, 42.0] Special values include:: >>> qp(0) 1.0 >>> findroot(diffun(qp), -0.4) # location of maximum -0.4112484791779547734440257 >>> qp(_) 1.228348867038575112586878 The q-Pochhammer symbol is related to the Jacobi theta functions.
