Changes in version 1.2.0 (2026-09-09)                  

  - iwishmom(): corrected the existence test for inverse moments. The
    moment of total degree k = sum_j j*f_j + iw exists if and only if
    (n-m+1)/alpha > k, i.e. n1 = n-m+1-alpha > (k-1)*alpha (real case
    n-m+1 > 2k, complex case n-m+1 > k). Versions 1.0-1.1 used n1 > 2k
    and returned NaN for some moments that exist.
  - wishmom_sym(): the printed coefficients were all divided by n (the
    formatting routine treated the coefficient of n as a constant term).
    The numerical function wishmom() was not affected. iwishmom_sym()
    was correct.
  - wishmom(), iwishmom(): the degenerate case k = 0 now returns m (or
    the identity matrix).
  - Vignette: corrected the statement of the existence condition;
    regenerated the wishmom_sym() example outputs from the corrected
    code; fixed a typo in the iwish_psr() example (iwsih_psr ->
    iwish_psr) and in the description of its k argument.

                 Changes in version 1.1.0 (2024-08-27)                  

  - Added wishmom_sym(), iwishmom_sym(), denpoly(), iwish_psr(),
    qkn_coeffr().

                 Changes in version 1.0.0 (2024-08-23)
