+
+```c
+#include "stdlib/stats/base/dists/weibull/mgf.h"
+```
+
+#### stdlib_base_dists_weibull_mgf( t, k, lambda )
+
+Evaluates the mgf for an weibull distribution.
+
+```c
+double out = stdlib_base_dists_weibull_mgf( 1.0, 1.0, 0.5 );
+// returns ~2.0
+```
+
+The function accepts the following arguments:
+
+-   **t**: `[in] double` shape parameter.
+-   **k**: `[in] double` shape parameter.
+-   **λ**: `[in] double` scale parameter.
+
+```c
