11: 28.34 Methods of Computation
  • (d)

    Solution of the systems of linear algebraic equations (28.4.5)–(28.4.8) and (28.14.4), with the conditions (28.4.9)–(28.4.12) and (28.14.5), by boundary-value methods (§3.6) to determine the Fourier coefficients. Subsequently, the Fourier series can be summed with the aid of Clenshaw’s algorithm (§3.11(ii)). See Meixner and Schäfke (1954, §2.87). This procedure can be combined with §28.34(ii)(d).

    All cases of R F , R C , R J , and R D are computed by essentially the same procedure (after transforming Cauchy principal values by means of (19.20.14) and (19.2.20)). … If t 0 = a 0 and θ = 1 , so that t n = a n , then this procedure reduces to the AGM method for the complete integral. … A three-part computational procedure for Π ( ϕ , α 2 , k ) is described by Franke (1965) for α 2 < 1 . …
