rayllike
              Negative log-likelihood for the Rayleigh distribution.
 nlogL = rayllike (sigma, x) returns the negative
 log likelihood of the data in x corresponding to the Rayleigh
 distribution with rate parameter sigma.  x must be a vector of
 non-negative values.
 [nlogL, acov] = rayllike (sigma, x) also
 returns the inverse of Fisher’s information matrix, acov.  If the input
 rate parameter, sigma, is the maximum likelihood estimate, acov
 is its asymptotic variance.
 […] = rayllike (sigma, x, freq) accepts a
 frequency vector, freq, of the same size as x.  freq
 typically contains integer frequencies for the corresponding elements in
 x, but it can contain any non-integer non-negative values.  By default,
 or if left empty, freq = ones (size (x)).
