29.7.6.17 Laguerre polynomials [sf.cmath.laguerre]
floating-point-type laguerre(unsigned n, floating-point-type 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 argumentsn and x.
Returns: Ln(x), where Ln is given by Formula 29.37,n is n, andx is x.
Ln(x)=exn!dndxn(xneâx) , for xâ¥0(29.37)
Remarks: The effect of calling each of these functions is implementation-defined if n >= 128.
