      2 {{alias}}( x, sigma )
      3     Evaluates the logarithm of the cumulative distribution function (CDF) for a
      4     Rayleigh distribution with scale parameter `sigma` at a value `x`.
      5 
      6     If provided `NaN` as any argument, the function returns `NaN`.
      7 
      8     If provided a negative value for `sigma`, the function returns `NaN`.

     10     Parameters
     11     ----------
     12     x: number
     13         Input value.
     14 
     15     sigma: number
     16         Scale parameter.
     17 
     18     Returns
     19     -------
     20     out: number
     21         Evaluated logCDF.
     22 
     23     Examples
     24     --------
     25     > var y = {{alias}}( 2.0, 3.0 )

     27     > y = {{alias}}( 1.0, 2.0 )
     28     ~-2.141
     29     > y = {{alias}}( -1.0, 4.0 )
     30     -Infinity
     31     > y = {{alias}}( NaN, 1.0 )
     32     NaN
     33     > y = {{alias}}( 0.0, NaN )
     34     NaN
     35     // Negative scale parameter:
     36     > y = {{alias}}( 2.0, -1.0 )
     37     NaN
     38

     42     distribution function (CDF) of a Rayleigh distribution with scale parameter
     43     `sigma`.
     44 
     45     Parameters
