raylrnd
              Random arrays from the Rayleigh distribution.
 r = raylrnd (sigma) returns an array of random numbers
 chosen from the Rayleigh distribution with scale parameter sigma.  The
 size of r is the size of sigma.  A scalar input functions as a
 constant matrix of the same size as the other inputs.  sigma must be a
 finite real number greater than 0, otherwise NaN is returned.
 When called with a single size argument, raylrnd returns a square
 matrix with the dimension specified.  When called with more than one scalar
 argument, the first two arguments are taken as the number of rows and columns
 and any further arguments specify additional matrix dimensions.  The size may
 also be specified with a row vector of dimensions, sz.
