+### Usage
+
+```c
+#include "stdlib/stats/base/dists/laplace/logcdf.h"
+```
+
+#### stdlib_base_dists_laplace_logcdf( x, mu, b )
+
+Evaluates the logarithm of the cumulative distribution function (CDF) for a Laplace distribution with location parameter `mu` and scale parameter `b` at value `x`.
+
+```c
+double out = stdlib_base_dists_laplace_logcdf( 2.0, 0.0, 1.0 );
+// returns ~-0.07
+```
+
+The function accepts the following arguments:
+
+-   **x**: `[in] double` input value.
+-   **mu**: `[in] double` location parameter.
+-   **b**: `[in] double` rate parameter.
+
