##### 1: 3.6 Linear Difference Equations

…
►In practice, however, problems of severe instability often arise and in §§3.6(ii)–3.6(vii) we show how these difficulties may be overcome.
…
►However, ${w}_{n}$ can be computed successfully in these circumstances by

*boundary-value methods*, as follows. … ►For a difference equation of order $k$ ($\ge 3$), …or for systems of $k$ first-order inhomogeneous equations, boundary-value methods are the rule rather than the exception. …##### 2: 28.34 Methods of Computation

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).

##### 3: 11.13 Methods of Computation

…
►For ${\mathbf{M}}_{\nu}\left(x\right)$ both forward and backward integration are unstable, and boundary-value methods are required (§3.7(iii)).
…
►There are similar problems to those described in §11.13(iv) concerning stability.
In consequence forward recurrence, backward recurrence, or boundary-value methods may be necessary.

►Problems on high-frequency scattering in homogeneous media by parabolic cylinders lead to asymptotic methods for integrals involving PCFs.
For this topic and other boundary-value problems see Boyd (1973), Hillion (1997), Magnus (1941), Morse and Feshbach (1953a, b), Müller (1988), Ott (1985), Rice (1954), and Shanmugam (1978).
