Sample Exponential random values with given shape and float dtype.

Parameters

key (Union[Any, PRNGKeyArray]) – a PRNG key used as the random key.
shape (Sequence[int]) – optional, a tuple of nonnegative integers representing the result shape. Default ().
dtype (Any) – optional, a float dtype for the returned values (default float64 if jax_enable_x64 is true, otherwise float32).

Return type

ndarray

Returns

A random array with the specified shape and dtype.
