(scale=1.0, size=None, dtype=<class 'float'>)[source]¶ Rayleigh distribution.
Returns an array of samples drawn from the rayleigh distribution. Its probability density function is defined as
\[f(x) = \frac{x}{\sigma^2}e^{\frac{-x^2}{2-\sigma^2}}, x \ge 0.\]Parameters: - scale (array) – Parameter of the rayleigh distribution \(\sigma\).
- size (int or tuple of ints) – The shape of the array. If
None
, a zero-dimensional array is generated. - dtype – Data type specifier. Only
numpy.float32
andnumpy.float64
types are allowed.
Returns: Samples drawn from the rayleigh distribution.
