val legendre_array : legendre_t -> int -> float -> float array -> unit

legendre_array norm lmax x result calculate all normalized associated Legendre polynomials for 0 ≤ l ≤ lmax and 0 ≤ m ≤ l for |x| ≤ 1. The norm parameter specifies which normalization is used. The normalized Pₗᵐ(x) values are stored in result, whose minimum size can be obtained from calling legendre_array_n. The array index of Pₗᵐ(x) is obtained from calling legendre_array_index(l, m). To include or exclude the Condon-Shortley phase factor of (-1)ᵐ, set the parameter csphase to either -1 or 1 respectively in the _e function. This factor is included by default.

val legendre_array_n : int -> int

legendre_array_n lmax returns the minimum array size for maximum degree lmax needed for the array versions of the associated Legendre functions. Size is calculated as the total number of Pₗᵐ(x) functions, plus extra space for precomputing multiplicative factors used in the recurrence relations.

val legendre_array_index : int -> int -> int

val legendre_sphPlm : int -> int -> float -> float
val legendre_sphPlm_e : int -> int -> float -> Gsl_fun.result

The parameters must satisfy m ≥ 0, l ≥ m, |x| ≤ 1. Theses routines avoid the overflows that occur for the standard normalization of Pₗᵐ(x).
