29 Numerics library [numerics]

29.9 Mathematical functions for floating-point types [c.math]

29.9.5 Mathematical special functions [sf.cmath]

29.9.5.16 Laguerre polynomials [sf.cmath.laguerre]

double laguerre(unsigned n, double x); float laguerref(unsigned n, float x); long double laguerrel(unsigned n, long double x);

Effects: These functions compute the Laguerre polynomials of their respective arguments n and x.

Returns:

where n is n and x is x.

Remarks: The effect of calling each of these functions is implementation-defined if n >= 128.
