+### Usage
+
+```c
+#include "stdlib/stats/base/dists/exponential/mgf.h"
+```
+
+#### stdlib_base_dists_exponential_mgf( t, lambda )
+
+Evaluating the logarithm of the [moment-generating function][mgf] of an [exponential][exponential-distribution] distribution with parameter `lambda`(rate parameter).
+
+```c
+double out = stdlib_base_dists_exponential_mgf( 2.0, 3.0 );
+// returns 3.0
+```
+
+The function accepts the following arguments:
+
+- **t**: `[in] double` input value.
+- **lambda**: `[in] double` rate parameter.
+
+```c
+double stdlib_base_dists_uniform_mgf( const double t, const double lambda );
+```
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+### Examples
+
+```c
+#include "stdlib/stats/base/dists/exponential/mgf.h"
+#include "stdlib/constants/float64/eps.h"
+#include
+#include
+
+static double random_uniform( const double min, const double max ) {
+ double v = (double)rand() / ( (double)RAND_MAX + 1.0 );
+ return min + ( v*(max-min) );
+}
+
+int main( void ) {
+ double lambda;
+ double t;
+ double y;
+ int i;

+ t = random_uniform( -1.0, 1.0 ) + lambda;
+ y = stdlib_base_dists_exponential_mgf( t, lambda );
