| ``mx.symbol.random_exponential`` |
| ================================================================ |
| |
| Description |
| ---------------------- |
| |
| Draw random samples from an exponential distribution. |
| |
| Samples are distributed according to an exponential distribution parametrized by *lambda* (rate). |
| |
| |
| **Example**:: |
| |
| |
| exponential(lam=4, shape=(2,2)) = [[ 0.0097189 , 0.08999364], |
| [ 0.04146638, 0.31715935]] |
| |
| |
| |
| Usage |
| ---------- |
| |
| .. code:: r |
| |
| mx.symbol.random_exponential(...) |
| |
