#### Associated Laguerre polynomials <a id="sf.cmath.assoc_laguerre">[[sf.cmath.assoc_laguerre]]</a>

``` cpp
|
| 4 |
+
double assoc_laguerre(unsigned n, unsigned m, double x);
|
| 5 |
+
float assoc_laguerref(unsigned n, unsigned m, float x);
|
| 6 |

long double assoc_laguerrel(unsigned n, unsigned m, long double x);

```

+
*Effects:* These functions compute the associated Laguerre polynomials
|
| 10 |
+
of their respective arguments `n`, `m`, and `x`.
|
| 11 |
+
|
| 12 |
+
*Returns:* $$%
|
| 13 |
+
\mathsf{L}_n^m(x) =
|
| 14 |
+
(-1)^m \frac{\mathsf{d} ^ m}
|
| 15 |
+
{\mathsf{d}x ^ m} \, \mathsf{L}_{n+m}(x),
|
| 16 |
+
\quad \mbox{for $x \ge 0$}$$ where n is `n`, m is `m`, and x is
|
| 17 |
+
`x`.
|
| 18 |
+
|
| 19 |
+
*Remarks:* The effect of calling each of these functions is
|
| 20 |
+
*implementation-defined* if `n >= 128` or if `m >= 128`.
