+### Usage
+
+```c
+#include "stdlib/stats/base/dists/laplace/quantile.h"
+```
+
+#### stdlib_base_dists_laplace_quantile( p, mu, b )
+
+Evaluates the quantile function for a Laplace distribution with location parameter `mu` and scale parameter `b` at a probability `p`.
+
+```c
+double out = stdlib_base_dists_laplace_quantile( 0.8, 0.0, 1.0 );
+// returns ~0.916
+```
+
+The function accepts the following arguments:
+
+-   **p**: `[in] double` probability paarmeter.
+-   **mu**: `[in] double` location parameter.
+-   **b**: `[in] double` rate parameter.
+
